I'm doing the 3 peaks fell race next year and starting to think about my training plan.

I would have probably followed a marathon scedule fairly closely. but most mean running 6 days a week. I'm currently riding 125-150 miles a week and was hoping to maintain this as much as possible as I want to be cat4 road racing at some point next year too.

Question is, has anyone successfully added a significant amount of cycling to marathon/ long race training schedule and reduced running to about 3 days a week and still done well, I'm aiming for a good time, not just getting round before the cut offs!

I was hoping to run 1 hill session, 1 8 miler and one 15 miler, and build up the longer run to 20 or more miles a month before the race.

Any advice out there...
