Mary Johnson
After working in the fashion industry for 6 years (and realizing there was way more to life than retail events and working behind a desk), Mary made a career transition in 2015 and joined the team at Ranfone Training Systems, in Hamden, CT, as a strength coach. She began coaching runners in 2016; and launched LRP in 2017.
She holds both USATF and VDOT02 coaching certifications and is a Functional Range Conditioning Mobility Specialist (FRCms). She has also undergone the Kinstretch Level I instruction certification program.
On the running coaching front: she has had the pleasure of coaching athletes of all levels and abilities - from sub-3 marathons to beginner 5ks. She believes in a slow progression and constant communication between coach and athlete. As a mother to two babies (a little boy, born in July, 2019...and a little girl, born in September, 2021) Mary loves working with postpartum mamas, and believes in meeting yourself where you are as an athlete, and flourishing from there.
Mary started running in 2010 as a hobby and whittled her marathon PR from a 3:44 to a 3:06, and her half marathon from a 1:48 to a 1:25. When the pandemic hit, she also decided to start exploring shorter distances, running a 18:31 5k and 38:44 10k in the fall of 2020.
She founded Lift | Run | Perform after speaking with several runners and realizing there was a need for running programming that supports the athlete as a well-rounded human: remembering that we all wear a lot of hats in life, and running needs to fit into it all with sustainability. She also wants to encourage more runners to shed their fear of the weight room, because a strong athlete is a strong (and fast!) runner.
She also writes the blog itsamarython.
Kirstin Ritchie
Kirstin grew up as a gymnast and walked on to the Bucknell Track and Field program as a pole vaulter. After spending one summer running with some of the distance girls, she was offered a spot on the cross country team. She went on to compete for two years as a D1 distance runner specializing in cross country and steeplechase. After graduating with a Bachelor’s of Science in Neuroscience, she moved to Boston to do research at Harvard Medical School. Kirstin graduated from Yale School of Nursing in the spring of 2018 as a Nurse Practitioner with a master's degree and a focus in Mental Health and Psychiatry and now works with students at Amherst College in western Massachusetts.
Since college she has taken her passion for distance running to the marathon first as a member of the Boston Athletic Association and then with various teams in Connecticut and Massachusetts. She has since run six marathons including two Boston Marathon finishes and three sub three hour finishes with a personal best of 2:54 when she won the 2021 Manchester City Marathon, six months after the birth of her first daughter, Teresa Grace. Beyond the marathon Kirstin has explored her range by competing in various trail and ultra distances including completing a 100k trail race and challenging herself at the USA Mountain Running Championships.
Kirstin has always been interested in the interplay between the body and mind, having seen first-hand how negative thinking, distractions, and self-esteem impact athletic performance. Conversely, she has seen how filling the mental skills tool box has had a significant impact on finding joy and success in running. She wants to help athletes appreciate and train their minds as tools for improved performance. A proud mama, she has a passion for working with women who want to continue their athletic pursuits preparing for, during and beyond pregnancy and birth.
Carly Gill Larios
Carly grew up playing soccer, and always found joy in running, but didn't get serious until her adult years. In 2015, Carly signed up for her first marathon in Philly and she lined up unsure if she'd finish 26.2 that day. She debuted with a 3:21 and a BQ. She thought this would be her only marathon -- not even close. Carly recently qualified for the U.S. Olympic Marathon Team Trials in Atlanta with her current personal best of 2:42;09.
In 2016, Carly started training more seriously, coaching herself and ran her second marathon at the NYC Marathon in 2:59 -- placing 60th female and astonishing herself and those around her (truthfully). She came back from a winter injury in 2017 to run her third marathon at the Berlin Marathon, knocking off another 10 minutes and shocking herself with a 2:49 -- good for 35th female and 5th American. Carly ran the Boston Marathon in 2018 in the epic monsoon-like conditions -- clocking a 2:55 in her third marathon major and another 35th female finish. She hired a coach after Boston in 2018 and ran a personal best, 2:47, at CIM in December 2018. After CIM, she wanted to really incorporate more strength training and take a spring season to focus on speed (and set some shorter distance PR's!). It paid off in Berlin 2019, where she set her current personal best and OTQ'ed by almost 2 minutes!
Carly loves set big goals for herself, but if she's learned anything, it's that balance and recovery are the keys to growth. As someone who used to count herself out before the gun went off, she's passionate about mental strength and positive body image in the sport. She hopes she can inspire athletes to dream big and work hard, while elevating patience and longevity in the sport.

She began her running career after running her first marathon at age 12 which was made possible by a non-profit program called Student Run LA. Student Run LA helps underserved students by granted them a covered opportunity to train for the Los Angeles Marathon. She crossed the finish line in 2003 and has been running ever since. Running is a very important part of her life and firmly believes that anyone can optimize their performance with a some solid work, consistency, and patience. Currently she is finding a lot of inspiration running out in the trails, but still loves road racing. She has ran over 15 marathons, 2 50k Ultramarathons and her current PRs: 3:22 full, 1:35 half, 42:35 10k, 19:39 5k, 5:35 mile. Through running she found a passion in sports medicine which led her down the road into sports physical therapy.
In 2015 she earned her Doctorate Degree in Physical Therapy and a few years later in 2018 completed an Orthopaedic Residency and earned her Board-Certified Specialty in Orthopaedics, One year later in 2019 she completed an intensive 1 year Sports Rehabilitations Fellowship. She has coached runners looking for guidance from the 5k all the way up to ultramarathons and launched her own running club in 2022.
Tempo Training Run Club was born in efforts to provide a safe place for women to train and deter harassment, over the course of the last few months is was grown into a loved local run club that caters to runners who are just trying running for the first time, to hosting runners training to OTQ for the marathon. Growing up in a Central American home and being a first generation American herself, her goal is to continue to support her underserved community that she has resided in for 30 years. Nowadays you can find her at her job helping rehabilitate patients or out running the suburbs of Los Angeles. She loves coffee, cuddling wither 10 year old Pitbull Zoey, and watching riveting documentaries with her husband.
Kaci, a native of Toronto, Ontario, was a national figure skater for Canada and the US, and competed at an elite level through her undergraduate degree. While running was always a personal interest and supplement to training, Kaci took an interest in long distance running upon retiring from her skating career and having the need to maintain a competitive edge and an unrelenting passion for physical fitness.
Kaci embarked on her doctorate degree in Physical Therapy from the University of Hartford, and since graduating, has shaped her career with a focus on sports medicine and rehabilitation for athletes. In addition to being a coach with the US Figure Skating Association, she has also trained youth hockey teams to achieve optimal on ice performance.

Kaci offers running coaching, PT consultations and gait analyses for clients who are looking to identify causes of injury and prevent future setbacks with targeted strength training based on gait abnormalities and muscle imbalances.
Mary Denholm
Mary has 14 years of experience competitively running. She ran XC all 4 years for her high school and DII in college at St. Michael's College. She ran her first marathon during her freshman year of college in 2006 - The Vermont City Marathon - and finished in 3:39:52 (A BQ at the time). She was the 2008 Vermont State XC 5K Champion (combining DI, II, & III schools). After college she took 6 years off from running while attending law school and her first few years of being an attorney.
In 2015 she returned to competitive running and ran a 3:03:22 marathon at Lehigh Valley. From there it took her 3 attempts to break 3 hours in the marathon and she chipped away at her PR finally running an OTQ after another 3 attempts to break the 2:45:00 time barrier at CIM in 2019. She raced the Olympic Trials Marathon on February 29th, 2020 running a PR of 2:41:08 and placing 51st in the United States.
Mary has run her all her other PRs in her early 30s as well. 16:56 for the 5K, 35:16 for the 10K, and 1:17:38 for the half marathon. She was also the 2019 San Diego USATF Women's XC Champion during an undefeated season.
Mary loves investing in the goals of others and helping her athletes learn to love the process of training like she does. Removing the stress of performance to know that fitness gained will pay off long term even if the time on a clock does not reflect the hard work the first time or even the first few times. Helping athletes find consistency over time and enjoying every step along the way in pursuit of big goals is what it is all about!
Stefanie is a professional trail and road ultrarunner for lululemon and Gu Energy Labs. She herself focuses on ultra distances, but she is passionate about guiding her athletes from the mile up to the 200 mile and multi-day events. She currently resides in Pine, Colorado up at 8,700ft with her husband, Mitchell, and two pups Pace and Shava.
She was born and raised in San Diego, having graduated from the University of California San Diego in 2010. She grew up playing various sports and running with her dad, but didn't turn to distance running until she was in medical school, as a way to manage her stress. Stefanie worked the finish line medical tent at the Chicago Marathon in 2011 and after seeing and treating the frontrunners, she knew her heart was in the sport. She completed her first marathon in 2012 and quickly dove further into the endurance sports scene. Stefanie grew her training and focus throughout her surgical residency and began to narrow in on what was possible for her in 2018. Stefanie is the 2021 USATF 100 Mile National Champion, multi-time Tunnel Hill 100 female champion, and has run three of the top ten fastest 100 mile times ever for a North American. She is ranked in the top ten in the world for the distance and holds the second fastest time ever globally on certified trail. She has extensive experience on numerous road marathons and dozens of trail and ultra courses.
Stefanie is a board-certified physician and surgeon, specializing in lower extremities and has a passion for treating athletes. She and her husband grew a private practice from the ground up in Lakewood and Golden, Colorado. She now provides remote consultations to amateur up to professional and elite level athletes looking for second opinions regarding their foot and ankle injuries. Stefanie is a monthly columnist for Trail Runner Magazine and Women's Running Magazine where she provides coaching insight with a side of medical and science background. She is also the co-host of the Making Strides Podcast, where she and her co-host, Carolyn Su, aim to make diversity, equity, and inclusivity a pillar of the sport and not simply a box to check. Stefanie is also a member of Relay, a collaborative running media and content group on Patreon.
Stefanie is passionate about running, but even more passionate about being in a healthy relationship with it. Having personal experience with balancing a professional career in medicine, training, coaching, writing, and family, Stefanie places significant importance on flexibility, adaptability, and training being a joyful addition to her athletes' lives, not a stressful one. She strongly believes that big, crazy dreams are for anyone, at any stage of life and from all races and backgrounds, and that it's never too late to become who you were always meant to be. Her favorite aspect about distance running is the ability to find yourself and thus your why, out on runs -- whether in training or in races. She places emphasis on and trust within process-oriented goals, with the knowledge that the results will come naturally as a result. Stefanie highly values the coach-athlete relationship and believes there is significant power in lifting her athletes up at every stage of the journey.
Nora first started running in high school while on the track and field team. However the longest distance she raced was 400 meters, and a “long run” to her was 3 miles. Things changed in college when she ran her first marathon, the Rochester Marathon, in 4:36. Since then, she has fallen in love with marathons, half marathons, and the process of training.
For many years, her goal was to ‘BQ’ and run the Boston Marathon. In 2017, she started working with Coach Mary Johnson, who helped her lower her marathon PR by 21 minutes to run a 3:32, a BQ at the time. However, when it came time to register, Nora missed the cut-off for acceptance into Boston.
Through fierce hard work, persistence, and a hearty dose of stubborness, she kept chipping away at her marathon time, finally self-coaching her way from the 3:32 to 3:21 in November 2020 at the Manchester City Marathon. While she finally has her BQ with a sizable buffer, she’s not done yet - Nora still has unfinished business with the marathon.
Nora lives and trains outside of Boston and can be found at many local races chasing down her speedy fiance. She considers herself a student of the sport and loves reading as much as she can about the science of running. She has spent significant time working in run specialty and loves geeking out over the latest running shoes.
Nora firmly believes that you do not need to have been a collegiate athlete to find running success later in life. She believes that dedication, longevity, and smart training are key to big breakthroughs. Whether you are looking to Boston qualify or break 5 hours in the marathon, she believes it is possible for everyone to achieve their goals. As a grad student working towards her Master’s degree in School Counseling, Nora is also passionate about coaching her clients from a place of unconditional positive regard, meaning she wants to support and know her clients on a personal level. To that end, she also believes that it is deeply important to nurture a love of running in her clients, which can mean adapting training to fit busy schedules, identifying the right goal to chase, and knowing when to press pause on training. Nora loves nothing more than working with runners to help them unlock achievements they never thought possible.
Erin Williams
Erin was a basketball and volleyball player growing up, but dabbled with some track (400 hurdles – major fail – and 800m – somewhat decent) in high school. Unsurprisingly, she was not recruited for track but instead played basketball at Army West Point. She scored 1,000 points, grabbed 1,000 rebounds, and was a 2x First Team Academic All-American during her career as a Black Knight. After graduating, Erin commissioned as an Engineer officer in the Army and deployed to do route clearance (IED detection) in Afghanistan. Running became part of her life after that deployment, and she used her first marathon in 2014 as a way to reflect and work through some of the more challenging deployment experiences.
After having her first baby in 2016, Erin trained with a team for the Army 10-Miler in 2017 and really fell in love with the art and science of training. She earned her RRCA certification in 2018 and began guiding athletes a few weeks later. Since then, she’s coached runners at nearly every distance and ability level – from couch-to-5k through experienced marathoner.
As a mother of 3 kids (ages 2, 3.5, and 5), a wife, and a military officer, Erin wholeheartedly believes that running should complement your life. She’s spent her post-kids time whittling down her 5k time from a 20:54 to an 18:52, and hopes to tackle her half marathon PR (currently a 1:36) in the near future. Erin and her family currently live in New York, but have called North Carolina, Missouri, Tennessee, and Massachusetts home in the past decade.
Meriah Earle
Meriah is a 2020 Olympic trials marathon qualifier and 3rd place finisher at CIM with a 2:34 marathon, but she didn’t start that way. She went from a girl who couldn’t run one mile without sitting down...to a woman capable of 26 of them in a row under 6min pace. This sort of progress exemplifies her most cherished truth about running, that she encourages all of her athletes to remember: consistent efforts get results.
Meriah started running at age 12 when her P.E. teacher approached her about needing more girls on the cross county team. Workouts back then involved multiple breaks to sit down and she was shocked when her coach asked her to try and run the whole way without stopping. 3 miles without sitting down?! Impossible! That year she was awarded the “Most Improved” trophy when she finally learned to complete the courses with only walk breaks (no sitting.)
Meriah moved on from middle school cross county to run high school track specializing in the 400m. She walked on to the track team at San Diego State and earned a full scholarship her sophomore year by running the 6th fastest time in school history (at the time) 2:10 in the 800m. She stepped away from serious running in her 20’s and returned to the sport in her mid 30s, driven by the desire to complete a marathon and simply check it off the bucket list. She ran her marathon debut at Rock N Roll San Diego in 3:16 and found her running competitive drive promptly restored.
All of her lifetime distance PRs have come over age 40, and include a 1:13 half marathon, 34:04 10k, and 16:32 5k. She truly embraces the idea that PRs can come at any age, and we should always continue to set big goals and test our limits.
Meriah continues to share her love of the sport with members of the running community. She serves as a coach and mentor for the San Diego Track Club, is an assistant coach at Pacific Ridge High School, volunteer coach at Cal State San Marcos, and has privately coached athletes virtually and in person, for over 4 years. She has USATF and VDOT02 certifications.
Cara grew up playing basketball and played through college. She scored 1,000 points at Clarkson University and tied the school record - bummer - for the most 3-pointers made in a season. She was also named First Team All-Conference and academic All-American during her senior year. After basketball season ended, she decided to pick up running as a way to stay in shape. Transitioning from basketball to distance running was tough at first, but she eventually fell in love with running and hasn’t looked back.
Cara started working with coach Mary Johnson shortly after she started her running journey. While working with Mary, Cara has run several marathons and half marathons. Her marathon PR is 3:43 and half marathon PR is 1:37. These PRs are from several years ago and she has some unfinished business with both distances.
On the coaching front, Cara believes in consistency and trusting the process. Cara has worked with new and experienced runners who have trained for distances ranging from the 5k to the marathon. She is no stranger to a busy work schedule and wants to help athletes find balance between life and training. As someone who has also experienced pre-workout and pre-race anxiety, she’s passionate about helping runners build their confidence and find joy in training and racing.
Cara is a Connecticut native who lives with her golden retriever, Leo. She teaches high school math - Algebra II and Geometry - in Connecticut with a goal of helping students gain confidence in the subject.
Mireille started running in high school through the Track & Field team. Though the love for running wasn’t quite there, she enjoyed spending time with friends and finding a sense of community at practices & meets. As a lifelong active individual, she continued to participate in other sports such as volleyball and dance.
It wasn’t until college that Mireille began to explore distance running. As an Exercise Science major, her course work consisted of sports psychology, biomechanics, health education, exercise physiology, and more. It was with this knowledge that she began training and running at the school gym, eventually going on to run her first two 5k races in college. Unfortunately, she suffered a setback in her health and fitness goals with the diagnosis of the autoimmune disorder Lupus.
After a couple of years of focusing on health, Mireille was able to rejoin the run community in 2015 and has not looked back since! She understands the power of community and how having someone in your corner can make a world of difference. Mirelle enjoys coaching a variety of athletes and has a specialty of new or returning athletes as she believes there’s room in this sport for everyone no matter what you look like and what your goals are. Equipped with her exercise science and public health degrees with a certification from USATF, she’s ready to help you reach those goals with a supportive, holistic approach to training.
Alissa hasn’t always been a runner, quite possibly the opposite for most of her life. That changed in 2015 when she signed up for her first half marathon (without having any clue how to train). That race lit a fire in her and she’s been chasing down big goals ever since.
Coaching came into the picture because she loves understanding the “why” behind her training. She hired her first coach in 2017 after self coaching to a BQ at the NYC Marathon, this experience led to her pursuing her RRCA level 1 certification along with reading every single book she could find about run coaching and theories behind training.
Alissa has a PR in the marathon of 3:00:46, half marathon of 1:24:52, 10k of 38:12 and 5k of ?? because she never runs them. She loves working with runners of all ability levels because chasing down big dreams has a different meaning to everyone - whether you’re looking to just complete your first race or have dreams of BQing, she would love to be a part of that journey. As a mom of two, Alissa understands the logistics of trying to maintain a training schedule, while working full time and also trying to make sure everyone gets everywhere they need to go. Running should add to your life, not take away from it, so if that means you miss an occasional run because your family comes first, she will always understand.
Outside of run coaching, Alissa is a Marketing executive in Cleveland Ohio where she lives with her pre-teen girls and two very demanding labradors.
Kristen Doornbos
Kristen didn’t start running until after college when she found herself in a lonely season after moving to a different state. What started as just a new hobby to fill the time quickly became about so much more. Running gave Kristen a sense of body autonomy while dealing with illness that ultimately resulted in having a G/J feeding tube placed in 2018.
Kristen is now an adaptive athlete who has finished multiple marathons, half marathons, triathlons, and is frequently in the gym lifting heavy. All of her PR’s have been “FTP,” or “Feeding Tube Powered,” which goes to show that adapting training to specific limitations doesn’t mean you can’t find success in the sport.
In 2020 Kristen got her Level 1 coaching certification through USATF. She’s been coaching other runners ever since, many (though not all) of whom are adaptive and have some type of disability or chronic illness. Her forte is creating a coach-athlete relationship where the individual’s needs and strengths are truly seen; where programming is specific to a runner’s health and life context; and where athletes are encouraged to bring their full authentic selves to the sport of running. She believes that achieving a running goal is best when done joyfully— if running overall is detracting from your enjoyment of life, rather than adding to it, something needs reworking.
Outside of run coaching, Kristen is a Licensed Massage Therapist and runs her own independent practice in Sports and Medical massage. She’s constantly emphasizing strength training as a means of preventing injury, and answers most questions from massage & coaching clients alike with her favorite phrase, “It depends.”
