My heels are sore from running in a circle on wood for hundreds of laps. I just finished up a 45 minute run and got around 5.5 miles in or so. I run slower than yesterday, but still a decent pace. It went well except for the heels. They are a little sore. I am guessing its from now almost 13 miles running on hard wood in a small circle over and over and over..... It is what it is though. I am glad to get some running in.
At some point, spring and summer have to get here. It's literally a fact. I keep telling myself this. At least by June it will be nice, I hope.
On a side note, if you haven't gotten a chance yet, head over to AthleteonFire for some great podcasts, workouts, etc. Scott does a great job with everything he does.
