HAYDEN COX

Head Coach

Hayden founded Railroad to offer a space where nonprofessional athletes are valued and supported. He believes that no matter your goal, you deserve a coach that will work with you with the same passion and resources offered at the NCAA D1 and professional levels. He's coached an American Record along with several national championships and Olympic Trials qualifiers. He sums up his training philosophy in 3 steps.

1. Prioritize long term over short term

2. Create and sustain consistency and joy

3. Vary workouts, paces, and race distances

In his 10 years of Athletics coaching, including stints at the High School and NCAA DI levels, Hayden has helped countless athletes achieve their dreams during his career.

Hayden is particularly proud of how each athlete developed. When Hayden met Anna, she wasn't sure she could run more than 40mpw after constant injuries in college, but wanted to become a marathoner. In two years of working together, Hayden slowly introduced higher volumes and she's since run 2:35 and qualified for her first U.S. Olympic Trials. With Alyssa, she was a 33 year-old mother-of-two with a 2:41:24 PR. She didn't have time for higher mileage, but needed to somehow find a 4-minute PR in her 7th Marathon to qualify for the 2024 Olympic Trials. With patience, a longer-term training plan, and speed emphasis, she crushed it and ran 2:36:29 to qualify for her 3rd Trials. Allen joined RR thinking he had reached his potential, but with a splash of speed and more effort-based training, his PR's dropped from (5k) 14:29 to 13:57, (10k) 29:44 to 28:44, and (Half) 66:32 to 64:13 in only a year.

Hayden stresses that these national-class results, while fast and fun, are as meaningful to him as the countless PR's and podiums of all his athletes. Here are some of his favorite moments:

Lauren Ohler, a college student at UT, runs a 5k PR at Baylor University competing alongside (and beating) D1 athletes all across Texas.
Scott Beardsley, a 40yo trail runner earns his first race win and sets PR's in the 5k, 10k, and Half.
Christian Schaaf, a D3 alum, joins RR after graduation and sets PR's in the 800, 1500, 3k, 5k, 10k, and Half
Emma Allison, a former HS XC runner, BQ's and sets a huge PR (placing 2nd) in her first marathon with Railroad.
Grace Marmaras, a working woman in DC, improves her Half by 19 minutes and finishes her first marathon.
Braden Videon, a former cyclist, successfully completes his 1st marathon, months later, he PR's by 15 minutes
Amelia Larkin, a HS freshman sets a school record and becomes the first Region Champion in school history

Hayden claims Kevin Jermyn as his biggest coaching influence, and is constantly learning from top American coaches, including Robert Gary, Jenna Wrieden, and others.

He works full-time as an attorney in Austin, TX and regularly works as an announcer for top U.S. races. In his spare time, he also volunteers for the USATF Men's Long Distance Running Committee and is a community XC/Track coach for The Griffin School. He has previously held coaching positions at Elon University (Assistant Cross Country/Distance Track Coach), Chattahoochee High School (Assistant XC Coach), Furman Running Camp (Assistant Director), Furman Running Club (Head Coach), and C.C.R.C. (Head Coach). He is a USATF Level I Certified Coach.
