Casey Comber

I'm Casey Comber. Originally from the Philadelphia area, I ran collegiately at Villanova University and professionally with the Under Armour Baltimore Distance group. After my recent retirement from professional running, I've continued my role as an assistant coach of DIII powerhouse Johns Hopkins. My Running Career: High School I grew up in Horsham, Pennsylvania, and ran for Hatboro-Horsham High School. As a sophomore, I ran 4:40 for 1600m and 9:50 for 3200m. The following summer, I shifted my priorities and made a big jump 4:19 for 1600m and 9:17 for 3200m. I eventually made the Foot Locker National Cross Country Championship (now the Brooks XC Championship) the fall of my senior year, which opened up opportunities to join elite college programs. I'm particularly excited to work with high school athletes who are serious about their development — it's a stage of the sport I know intimately from my own experience and am actively building expertise in as a coach. College I went to Villanova University, joining a program with a deep middle-distance heritage and coached by four-time Olympian Marcus O'Sullivan I improved steadily thanks to a scientific approach to training, including heart rate and blood lactate monitoring. By my senior year, I became an All-American in cross country (10k), broke 4 minutes in the mile, and qualified for the Olympic Trials in the 1500m. In the following months, I signed an endorsement contract with Under Armour to continue my running career as a professional. Highlights from my college career: -Mile Personal Best of 3:57 -2-time Penn Relays Champion (2018) -Runner-up in the Mile at the 2019 NCAA Indoor Track and Field Championships -2021 Olympic Trials Qualifier in the 1500m Professional In October 2021, I joined Under Armour's professional athletics training group based in Baltimore, Maryland, coached by renowned coach Cory Leslie and supported by strength and conditioning coach Carrie Lane. Highlights from my professional career: -Mile Personal Best of 3:51 -Bronze medal, 2023 Pan American Games 1500m — Santiago, Chile -2024 U.S. Olympic Trials 1500m Semi-Finalist -Two-time BAA Mile champion — Boston (2024, 2025) -2nd place, USATF 1 Mile Road Championships (2023) -Pacemaker for Grant Fisher's 3000m indoor world record (February 2025) -Marathon debut: 2:31 — Baltimore Marathon (October 2025) Coaching Career Over the last three years, I've assisted Johns Hopkins Track & Field and simultaneously developed workouts for local athletes of all levels for Under Armour's Track Tuesday. I recently decided to expand my private coaching business to bring private, individualized coaching to runners of all backgrounds — high school athletes, post-collegiate, masters runners, recreational competitors, and adult distance athletes who want to take their training seriously. Every athlete gets a custom-built training plan, weekly adjustments based on how the work is actually landing, and direct access to me for the questions that come up between sessions. Recent coaching results -1500m and 800m 2026 Maryland Games Masters Champion -2027 Boston Marathon Qualifier My approach borrows from my own development at the highest levels of the sport: build the aerobic engine first, develop event-specific speed in season, train the head as deliberately as the legs, and respect recovery as a non-negotiable part of the work. Within that frame, every athlete's plan looks different — because every athlete is. Together, we'll make sure your training plan fits your schedule and lifestyle. I'm based in Baltimore, Maryland. I bring the analytical rigor of the programs that shaped me as an athlete to your training. Baseline lactate testing is available for local athletes. Reach out today!
