I'm now sporting a new pair of Nike Lunarglide+ shoes. My old pair of Asics was getting very soft, and I could tell the heel wasn't providing much in the way of rotational support. One very interesting observation is just moving the Nike+ sensor from my old shoes to the new ones resulted in slightly different (faster) speed & (farther) distance readings. I had the sensor taped in the tongue of the Asics because they didn't have a dedicated sensor pocket. I'm guessing the impact force readings are much different in the floppy shoe tongue versus the sole of the shoe. Or maybe the new shoes just make me faster!
I've been running 2 -3.5 miles perhaps three or four days a week now, mostly just to try and keep our dog somewhat tired out so she won't rip the house apart when I am at work. I've also been hitting the weights during lunch with the guys from work with a pretty intense program. I think this running and lifting will help my bike performance, but I don't think it's a total substitute for miles.
I'm starting to get a little concerned about the Dakota 5.0, I think I need to put together a honest to goodness training program to prepare.
