Stretch your hips after riding too. This will prevent ITB injury that folks have talked about. Just sit on the ground with your legs in front of you, and cross your leg over the other, with the knee up. Pull your knee towards the opposite collarbone with both arms, kind of like you are hugging your leg. You will feel the stretch. Repeat for the other side.
