Desert Training Advice

johnny-marrone

I've switched from marathon running (sub 3.30hr marathons) to cycling and am trying to get 'cycling fit'. I'm stuck out in the desert for a few months and am unable to cycle but do have access to a decent gym. I've been using a spinning bike and making up my own programme lasting about 45mins however, I'm not sure if it is particularly effective. The gym also has all the normal leg presses, running machines etc. Anyone out there who can give me some advice? Not too technical please as I've left my HRM at home.

thanks
