my understanding of peaking in a gradual build-up of speed/intensity 10-12 weeks prior to competition. my concern with IM training is that if you build up your volume at low intensity (ie. 80/20 Z1/Z3 split) can you avoid peaking too early? I have 17-weeks to before my IM event but am feeling that I am coming off a good winter and now that spring is here I feel that my goal of 20-hours/week is easily achievable. should I resist and back off or carry on and keep maintain the volume?

on another note, anyone against doing an OLY 3-weeks before an IM? If so, why?
