I will preface this story by saying that I had a painful run on Thursday evening (and it was only a 3 mile run). My heel/arch on the underside of my right foot started hurting... so after about 1.5 miles, I just walked home. I took Friday and Saturday completely off (hoping to heal up a little bit). My initial race expectation/goal was to finish at or under a 10min/mile pace for the race. With this pain I was having... I was starting to feel a little uneasy about that goal.
I still didn't really care that I was injured -- I was successful!! :)
