40 mins for a 10K is my (longish term) goal. I'm 37, 5ft 8 and weigh 12.5 stone. I'm comfortably a stone overweight and it's all in my gut. I've dipped in and out of gyms many, many times before but I've never felt as motivated as this, albeit I'm only 2 weeks in.
I'm setting myself mini goals such as be down to 12 stone 3 by the time I go to New York, be under 12 stone for my mates party at the end of March. It's baby steps but I think it's a better way to do it than going big bang. That's four days in a row now I've been to gym and 7 in the last 12 where I've probably not done 7 in the 3 years before that!!
There's a Glasgow 10K in October so that's my goal to get my fitness levels up in the gym, then get out in the road and be able to put in a sub 50 minute for that. After that I'll probably win the London Marathon.
