THANK TOU guys! Exactly what I was lookin for

I wear night braces and I have orthopedic support in my shoes and I did 5 miles on majority flat trail and my heels didn't hurt at all ( stretched before, middle of and after). my podiatrist said that I can exercise just has to be minimum but I really think that doing 10 miles 2/3 times a week will help me SO much mentally,like I said I'm not racing lol
I'm going to a bike store today to flat out details on a bike and such
It's bitter sweet to know there are other people trying to beat Achilles too, Constantly feel like I'm alone :/
