Is there an age limit to the fitness challenge?

Hey Guys I downloaded Reddit just for this I'm not gonna say how old I am but I'm a junior (this year). I wanted to compete and have been on the fence about it since it's announcement but didn't wanna be weird. I'm about 6'0 180 and am a varsity wrestler so with season coming up I figured I'd do the just get fit thing. If I can't compete I'd still love to support or anything I've been lifting since I was 8 and kinda know what I'm doing. Thanks guys.
