run cadence vs bike cadence (Page 2)

How can running be this complicated?

As I understand it, having a high cadence on the bike (around 90 revolutions per minute) will yield the most efficient use of power. This is compared to pushing a larger gear with a lower cadence or a smaller gear with a higher cadence. Cyclist like Lance Armstrong and Ivan Basso are prime examples of subscribing to this philosophy. As for running, having a high cadence or turnover, while being very important for efficiency purposes, has the added benefit also of reducing potential injuries. A high run cadence causes your foot strikes to land beneath the body and not out in front as they might with a slower cadence. From my experiences I've found it easier to adopt the optimal cadence on the bicycle versus running. It sounds like your having the same problem too. To answer your question, I wouldn't slow up your bicycle cadence to be in accordance with your run cadence. I think that would only be a disadvantage with regards to your cycling with no corresponding advantage to your running. Best of luck!

With all this talk of run/bike cadence should I pick up the Polar Cadence sensor to go along with my s625x hr monitor for the bike to help with my bike cadence?

Sometimes when I ride with my wife I will push a hard gear for the whole ride and not change gears producing a low cadence, kind of like a fixed gear bike. Or would it be best to go to a lighter gear and and spin at a high cadence for the whole ride? I like to stay with her but since I can't ride at my pace I'm still looking to get something out of it.
