Post Tibial Tendonitis

Too much too soon?  My guess is that my legs were not as ready as my mind was for the 18.4 mile trail run almost two weeks ago.  I felt tired but felt no sharp pain to make me consider stopping during the run.  Looking back on it I probably should of laid off the gas and mileage that day.  I ran all 18.4 miles including the uphills (passing mtn bikers) and it was also my longest run on all trails.  I think all of this along with my 14 and 8 mile run earlier in the week made my legs give out. Not smart.  I pointed at the pain in my ankle and before I could finish my sentence my bro-n-law who is an ortho foot surgeon said, "Post Tib Tendonitis...".  Hearing the name of the injury was in some ways relieving because now I knew exactly what I needed to research and do to hopefully heal the injury.  John gave me a few pointers for recovery and I hope to be back on my feet running soon.  I've managed to stay cardio fit with some long bike rides but feeling the need to start running again.  I have 7.5 weeks to go before my "race" and all I want is to be healed and running again.  I'll attempt to run tonight on the treadmill and see how the ankle goes.  I purchased some insoles to give my arch some support, I've been stretching the crap out of my calves and massaging my tendon as much as possible.  I know I can still do this race. As far as how fast...I'm not sure.  I can do this.
