PH: I used to rotate shoes, but am currently trying (and failing) to find a "holy-grail" pair of shoes, in which I can train with some intensity without tearing up my calves. I was rotating last month during my last injury = trying some new shoes with no rotation (Asics Kayano).
BnB and other cyclists: I received
this Spinervals dvd for Christmas, and tried it for the first time last night. Even though I only went through the first 55 minutes, It was undoubtedly the best indoor ride I've ever had. I'm hoping to use it once a week while the weather is cooler, while adding 10-15 additional minutes each time I do it. Hopefully I can kick all 2 hours within the next 6 weeks. Most notably, they place the best looking female in the very front of each set of intervals, and allow her to bounce a bit more than the rest of the participants (quality directing decision).
