A.M. 10 with Jeff in 1:14:59. Benjamin ran the first 2 with us in 15:37. I have transitioned to running on pavement instead of grass. Seems to make no difference for the foot. The dull pain is still there, about the same before or after the run. Day of rest does not do anything for it.
The speed does affect it though. I believe it has to do with the fact that due to more vigorous movement it becomes difficult to keep the heel from touching the ground hard. At slower speeds I am able to land on my toes and gently lower the heel later.
Could this be a minor stress fracture?
