One of my observations from the posts is that at the higher level you would need running specific training to run... a faster marathon. General cardio fitness from cycling would go only so far, but definately a big help to achieve 4hr marathon.</p>

<br><br><p>My observation is that specific marathon training would raise your threshold pace, allowing you to run at a higher level. Since you are not doing a lot of near or over LT runs, most likely, general bike fitness will allow you aerobically hold something a bit faster than say E-pace for a period of time. For example I did a marathon training run a few years ago while IM training, where I was running 20-25 miles a week, nothing really fast, and held a just over 8min pace for the entire thing. 8min pace is something I was use to running in most of my training runs in z2. I average a z2 workout for the 26.2 miles, bleeding into z3 at the end. However I was in no shape to run anything higher for that duration. I think in a marathon, like Mike, may run something much nearer his threshold and maintain it the entire time because he specifically trains for it. I could never have done that during my IM build up as I train at a slower pace, supplemented with a lot cycling.</p>
