I am planning on doing a double century (STP One-day) in July. I have had consistent mileage throughout the "winter" of about 70-80 miles per week, but most of these rides are rides of 6-8 miles or less, 8-10 times per week, and maybe one day with 25-30 mile rides.
Due to various work/family commitments, it is easier for me to ramp up to get more "short" morning rides of 25-40 miles, 4-5 times per week, plus my normal commute home of 6-8 miles.
Can I train primarily with these base miles, or is it necessary to have multiple, long rides (century +) under my belt?
While I do plan on taking some longer weekend rides, I don't plan on those being my primary miles. Should I worry or change my plan?
