I've been doing it on and off for a couple of years... usually 5 or 6km, but anything up to 15 if I can get motivated for it. usually road, but sometimes trail. I still prefer biking, but it's a way to get out with friends, and I get a lot more exercise done in 30 mins of running than I could in 30 mins of cycling (that's about all the time I ever manage to get free at one go!)
Have been meaning to try and get into it seriously - I have some friends who now do marathons and half marathons or 10/15k races almost every week. The first is a cyclist turned runner who can now knock out a marathon in 3h27 and a half in about 1h30, the other did very little exercise at all until about 5 or 6 years ago and his time for the local marathon last year was 3h13m :shock:
if I could even just finish a marathon, I'd be quite chuffed with myself! I keep trying to start training for one, to give me something to aim at, but other stuff and lack of motivation always get in the way :facepalm:
WD, I know I should know where that pic was taken - it rings a very large bell somewhere in my memory, but I can't for the life of me remember where!
