Hi, this is my first post. This is a great site. I looked over a thread of this subject and the virdict seemed to be that running was not very helpfull for bike training. I'm not too sure about that.
I have recently returned to the cycling world after being a full time competitive runner for five years. As a result of an injury this summer, I got back into bike riding. When I came back I found that I was a better biker than I ever was before. What I noticed most was that I felt incredibly powerfull on the hills. Infact, my riding companion (who has been an avid biker for the duration of my running and even before then) was no match for me up long steep hills. In a 50 mile mtb race I did, no riders could contend with me on the hills.
Now, obviously my aerobic values were way better now than when I biked before my running bout and I am older. But after not biking in 5 years and doing so well (especially on the hills) I have to wonder if running conditioned my upper leg prime movers to be relatively more powerful. I thought about this a lot after reading about "power cranks" where the main idea seems to be that you can derive immense power by pedaling with only one leg at time without the help of the other leg. I think this may be similar to running, where you also lift only one leg at a time.
Is there any truth to this, or has my immense power and strength increase just been a result of the years of aerobic conditioning I got with running of other factors?
Consider also I biked when I was 14 and 15 years old, ran from age 15 to 19 years old, and returned to biking also at the age of 19. I am 140 lbs and 5' 11
