Thanks very much,
I'll try, 15 min warm up, 30 mins @ 80/85% with 15 mins cool down. If that goes allright I'll go for the 30 mins @ 85/90% a couple of days later. If you both use it, it can't be bad.
I know what you mean Neil, but it's something I need to do. Physio said that I could start using the eliptical trainer from Sunday. I'm fed up with the pool & the bike in the gym and I can't get a structered tempo seesion on my off road bike.
Editor, if I could run, believe me I Would.
