Despite a fair amount of experience in running more than 10k, I still have to figure out what the trick is to avoid getting blisters. Today after 21k my feet look like this.

I have a fair amount of callus and I have good shoes and good socks, but none of that helps. The speed also doesn’t seem to effect this outcome. I can run slow or fast (… by my standards), but the result is the same.

Admittedly, the blisters don’t really bother me, and I only noticed after my first marathon that I actually had blood in my shoes, but I still hope that at some point I’ll be able to get rid of this annoyance.
