I'm an exercise addict! I ride 4 days a week, run 1, hit the gym 3 times and soon, I'll be playing baseball twice a week (no days off - I know bad). I accept doing all this actually hurts gains in each sport, but I just love being active! I can't think of a day a in the past couple years a body part hasn't been sore (especially legs)
I do race on the bike and run and know I'll just be in the pack finisher.
The only benefit I've seen from weight training and cycling is explosive power. I've got a pretty good jump, but that's about it lol.
