I've always been a decent runner, but at the end of November I decided to up the ante, after an elderly woman I'm friends with (in her fifties and already retired) managed to run 230 km in one month. (143 miles).
Naturally I took exception to that and decided that I'd find the time to run at least 10 km every day for the month of December, with one day of rest allowed.
Things didn't go as planned. At all.
