This winter I've been doing quite well without a car. Although the weather has been mild enough to bike, I've mostly stuck to walking. And although mild, it's still cold enough that I put on water shoes to go running most of the time (my absolute cutoff for running in bare feet is 35°F when it's wet out and 20°F when dry; usually I transition when it's warmer). And then it wasn't snowy enough to go cross-country skiing except once or twice. And then I got a dog and we'd run together in addition to one more time walking.
So 20 miles a week running in addition to probably 30 miles of walking started taking its toll. A few weeks ago I noticed my left Achilles tendon was a bit sore. I persevered as this kind of thing happened before and that seemed to be fine. But more recently, I just wasn't willing to push through it to run as the pain became too great. I've dropped to about a mile a week, and will cut back even more. I had heard how the body is typically able to repair damage from normal use as it happens, but if it starts falling behind, the result is a repetitive stress injury. I'm just going to assume that's the case — rest and gentle treatment cause the symptoms to nearly disappear, and aggressive use brings them back.
Fortunately I've found that bicycling doesn't aggravate it nearly as much so I'm switching back to that. In turn, that is motivating me to get the bike projects done that I have partially completed. Unfortunately, it looks like I'm going to sit out the Lilac 5K this year.
Nonetheless, I see the sexy young women out running these early-spring days and all I can think is, "gosh, I wish I could get back to running."
