Founder & Head Coach
Hi, I’m William.
Runner since 12, triathlete since 2007, coach since 2009. I built Fly Tri Racing on one idea: great coaching comes from trust and consistent communication, not a cookie-cutter plan.

“From going to a 4:37 marathon in 2022 to coach Kevin Green training me and getting me to a 3:25 at the BMW Dallas marathon a year later.”
Layne C. | Palestine, TX
“Took me from a novice triathlete non-swimmer to decent 6 hour age group finisher in Texas Ironman 70.3 with 6 months of training.”
Matt A. | Longview, TX

Bob M. | Charleston, WV
“Coach Ritter’s professional approach to communication and coaching thru her high-school running career has been top-notch.”
