Now in it's 4th year it's a staple of the winter running scene in Scotland and beyond. It's easy to keep up with everyone's progress either via the website, a Facebook group, or an account on Twitter.
The rules are pretty basic. You must run a minimum of three miles or 25 minutes - whichever comes first, every day in December. There are no prizes, just a personal challenge to get up and run every day for a month.
I decided to take part this year after seeing a club mate, Mike Newton, do it last year. He got a real boost from it personally and he managed to run 170 miles in the month. That's more mileage than I've ever managed to do in a single month so I thought it would be of benefit to me as I attempt to run some longer ultras in 2013 and also to inspire me to get out for a run on those days where I normally wouldn't feel up to it.
UPDATE: I managed to run for 16 days in a row before I had to stop due to injury. I ran 97 miles in that time. I really enjoyed it but I was pretty worn out by the time I stopped on Day 16.
I'd never run more than 7 days in a row before so it was a good achievement even if I didn't complete the whole event.
