Notes
Around mile 11 or so on Margarite, a pain or cramp appeared in my left foot just behind the ball of the foot. Adjusting my position never really cleared it up. It got a bit worse for the next mile then leveled off for the remaining distance, though going uphill was worse than on level or descending ground.
It was there most of the day, though much lighter. It went mostly away on friday and thankfully it totally disappeared by Saturday for a 4mi shakeout run.
