Rotation

On the bike yesterday for 50km.  Averaged just over 33 for the first 45k, felt great the whole time, one of my fastest rides ever for sure. Hit some heavy traffic coming back up North road through so that wasn't ideal. Then did a core set which hurt so much as it always does. Rolled and stretched in the evening and made sure everything was still working. It was, although my hamstrings are so tender because of the fast finish Monday night. About to roll some more now.
