Can anyone help? I started running in June and have progressed to 30mins three times a week in the gym (some hills) and two one hour outdoor runs. I go slower outside (the opposite to what others seem to find!) and do about 10-11 minutes miles I think (running in a park, so not sure of distance). Cardio wise I am loads fitter - do cross trtaining and weights x3 per week - but I find on my outdoor runs that my legs just give out by an hour. I can't seem to push them any further, have tried doing an extra 5 mins, and running without a watch, but no joy. I want to do a half marathon next year and the FLM in 2004, but can't imagine how. Any ideas please......
