After the ResPass 100 I ran two more races, the Lost Lake Trail Run in Seward in late August (15.75miles) and the Equinox Ultramarathon in Fairbanks in mid September (40miles) after that I took 10 weeks off from running to figure out what's going on with my Posterior Tibialis Tendon.
This is something I have dealt with off and on for the past 3 years, but culminating with daily pain after the Equinox Ultra. My ortho recommended 6 weeks rest and then re-evaluating, after which it wasn't any better and he referred me to an ankle specialist. 2 more weeks till that appt. and he said, "yes, surgery to re-align your foot could work, but I won't do the surgery on you." I have Posterior Tibialis Tendon Dysfunction (PTTD) or acquired flat foot. My tendon currently has tendinosis, which is structural damage in the tendon on the cellular level. It is progressive, but the doc said that right now I have good tendon function so he wouldn't want to do surgery as it could mean my end to endurance running. He said I might need it eventually, but not guaranteed.
The Tx is to wear custom orthotics at all times, ice, rest as needed, and listen to my body. So I went for my first run in 10 weeks on Tuesday night, the Pub Run. Only 2.88 miles in 27 min. but was great to get out and reacquaint my lung, legs, and mind. Looking forward to ramping up my running and then start training again in late January.
