Grant Koontz started racing a bike in his senior year of high school. He was diving and then jumped on a bike. The Houston, Texas native says his physical talents didn't mesh with football to basketball. 

By the time Koontz got to college he'd won a national time trial championship. He credits the riding community of Houston for giving him direction and guidance. He says several older riders taught him riding etiquette. 

Koontz got so good for 10 years he raced on the road. He eventually went pro and landed not the Holowesko - Citadel team for a season. 

In 2019 he went  to a national track camp. Koontz eventually went to T-Town to race and train. He ended up winning a National Championship in 2019 and 2021 in the team pursuit. Koontz killed at nationals in 2022 by taking titles in scratch race, points race, and the Omnium. He even won the scratch race at the Pan American Track Championships. 

This year he recently won the Madison Cup at T-Town. At the moment he's focused on racing in Europe this winter.
