I'm an intermediate road cyclist wanting to fit in a little more training. Found out we have a shower at work so I'll be doing my hard rides (M,W,F or T, TH) on the 12-mile MUP that goes downtown. The big question is: would you go just as hard on the way back home in the evenings or would that be overdoing it? I normally ride to work (at a slower pace on my commuter bike) with training rides in the evenings and longer rides on the weekends.
