I second the cycling clothes. DH and DS are into cycling. They just got back from a nearly 400 mile, 1 week ride. The longest day was almost 70 miles. DD loves his bibbies. They also have padded crotches to help with butt fatigue. DH swears by the Hammer Gels for energy but IDK if they really work. Make sure you are properly fit for your bike. Its amazing how having your seat a smidge to low or high can affect the way you ride.
