Twice over the last couple days, I have had a shooting pain in the bottom of my foot. It wasn't when I was running, but I immediately thought of Plantar Fasciitis popping up. I rolled my feet yesterday after my run and today before my run, noticing some foot pain today. It may just be because I rolled them with a lax ball pretty deeply yesterday.
As I write here, I am rolling my feet again, focusing on my right one. I cut short today's run from10-15, down to a solid 6 miles at 7:57/mile pace. I was running in the snow and slush after this morning's storm, enjoying the warmer temps up at around 30 degrees. My training is going well, therefore I don't want to overdo it when a little caution could help me in the long run.
I have kicked up the weekly mileage higher than I have ever consistently, so a little added soreness here and there is to be expected. However, I don't want to ignore early signs of real problems. We will see how I feel tomorrow and I plan on keeping to some slower miles over the next two days, followed by Saturday and Sunday off.
Here is a good article about Plantar Fasciitis and everything that goes along with it, from a non running perspective.
