Tom: Oh, not without a single stop. We stop briefly along the way to take a drink in the shade or eat a snack (I dislike eating/drinking while riding in traffic) or to walk the bikes across a busy street to continue along the bike trail. But I didn't notice any butt soreness until we were almost home at the end of the 30 miles.
