During last Tuesday nights run (a PB 5km in 22:15), I developed one heel blister on each foot. The right foot was pretty minor, the left foot was a good blister.
I taped up the inside of my shoes and feet for my other runs and didn't have any further problems. Good.
It rained today, so I couldn't bike to work. After Darcy was in bed I went out for a brick. A 10km ride and a 5 km run. Well, 3.3km into the run I had to stop. I had torn the blister off my left foot. I decided that if it was bleeding then I would stop. If it wasn't bleeding I should probably still stop. It was bleeding and I was about a mile from home. So I took my shoe off and walked.
Fortunately a friend of ours lives right along the route I was going and he was out cutting his lawn. We chatted a bit and then he gave me a ride home, that was a good thing.
So I'm two and a half weeks out and I have an injury. That bites. "Bandaid" is supposed to have some good blister bandaids. Look for a review shortly.
