I hesitate to say Parkrun, but I just did my first one. Ambled around, ran all the way but slowly and didn't push too hard, had some lovely tunes playing, no MapmyRun or anything so have no idea of the time but I'm actually not bothered which is great, because I thought I would be (Came in about 15th from last but who cares I guess I'll get faster!)
There was a real carnival atmosphere because the Marathon is tomorrow and the Mini Mile later today, so all the barriers and tents were up in the park. The barriers meant it was very narrow at the start so we all had to walk for the first 30 seconds or so, and it started throwing it down with rain halfway round but I'm so glad I've done my first one.
Also...if anyone is interested, Garmin 10s are cheap on Amazon at the mo, I picked up a lilac one for £53 (inc post). No more trying to fiddle about with iTunes/MapmyRun, and I can go back to my trusty old iPod!
