I’ve been riding for 3 years, been on TR for 2. Never done a race; hopefully, I may get to try one soon. I have been using TR to get better at my weekend group rides ( riding with a bunch of older fast guys 10-20 years older :() and get fitter. 2 years ago I was getting dropped on warmups(15-18mph). Currently able to keep up with 26-30mph sprints and still getting better. Plus I don’t need to be in a crowded gym to get fitter and healthier and it is FUN!!@!!!
