The Thunder Challenge is a 5k and 10k event series designed, owned, and operated by US Military Veterans. Our goal is to provide everyone with something that will be fun and challenging at the same time no matter your experience or fitness level.

We offer competitive heats for those under 18 in the 5k event series and for those Elite Pro Racers we have competitive heats in the 10k category as well. Everyone can run and everyone should come find out if they are Thunder Tough!
