These days, all of my training is done on trails and I credit the soft surface and varied terrain for staying injury-free for as long as I have. That said, when I stepped out of bed yesterday morning, my right heel screamed in protest — and I immediately started listing injuries associated with heel pain. Plantar fasciitis was at the top of the list. I took a look at my running shoes and, despite being filthy from the trails, they looked great — none of the telltale heel-wear that I associate replacing shoes with. Then I checked my Daily Mile training log and immediately stuck my tender heel in a bag of frozen corn. Since buying my shoes in December, I’d racked up 726KM on my current shoes — well over any sensible distance. The miles that went into ultra marathon training snuck up on me and I broke all of my own rules when it came to replacing running shoes.
