I foolishly signed up for a triathlon in the desperate attempt to lose weight. However I have since realised that beginners do the sprint and I am doing the standard. I have 11 weeks to go and am 3 stone overweight. I have lost a stone so far and have gone from not being able to run at all to getting to 3.7miles in 46 minutes. I swim breaststroke and can do the distance in an hour, but I am desperately trying to crack front crawl with head in water (I always thought I was a good swimmer until I tried to do it properly). Cycling is ok again not fast but I have a crap bike that of course I will change. Now I am happy to come last and even to be a hour behind the second to last person, it will be such a personal achievement for me, but my concern is the organisers and stewards being hacked of with me for being so unprofessional and slow. Should I pull out!
