My trip will be at least 24 miles each day, M-F, from May to August. (I plan on continuing beyond August but it will be 2 days each week.) The commute-to will be from 5 am to about 6:30 am, which is rush hour. Do any of you bike 25 miles a day, 5 days a week, in heavily urban areas with fast cars? If so, do you have much energy afterwards? Thanks again.
