The day after my Shoreline Shuffle race I had some weird pain in my left calf. I thought for sure it was a stress fracture from pushing too hard on the trail. After some rest and applying R.I.C.E. for a few days it appears to have gone away. I ran 3 miles on the treadmill last night and had no pain at all. I'll give it another couple days of treadmill runs before heading back out on the road.
