I am going to be entering a TT race in a few months. It's a short course, 5 miles. My question is, can I train most of my time on an I door trainer and expect good performance on the actual TT race, versus training on the road? The road around here is not too good to go all out full force and really test my endurance and strength. Too many potholes, crazy drivers, and just not enough space to get a good hardcore training session in. A long cruising 15-20 mph average for 8 miles or so ride, yes, but anything more than this is too difficult with the conditions I face. Would I be able to get good training done for a Time Trial using an indoor trainer? I was thinking since a TT has little techniques regarding racing in a bunch, and drafting and so forth, an indoor trainer would mimic the balls to the walls training I need outside of a highly controlled smooth road. Which I don't have:/ Thanks for your time Mike
