I suffered from this for a year... Yuck. It can be difficult, did gave good luck with the PF "boot" you can get from walgreens. You sleep in it and it helps to stretch out your foot/heel. Good luck!!
Hi, new here. Used C25k a few years ago and got up to 20 mi. Biggest regret was not going to the marathon I had trained for. Now completely out of shape, chunky and ugh..... Older! Going to give it a shot again!!! Nice app!!
