Training for 16 mile team time trial
I am planning to enter a 16 mile two-man team time trial in 9 months. I typically ride one hour per day six days per week either on a stationary bike, a single speed mountain bike or fixed gear road bike. The course (with three climbs and three fast descents) seems inappropriate for a fixed gear. I do own a geared road bike, but I rarely ride it.
I would greatly appreciate any advice on training. If it makes a difference, I am 45 years old.
Many thanks.
