Re. wheel movement in sprints. I've got my sprint back up over 1300, and I guess due to me not being used to it lately I had some wheels moving around. It happened years ago when I first started sprinting but went away quickly.
Today was 4x8 w 2' rbi again (after back and bi day... if I end up racing should I worry if my biceps get too big? I'm eligible to race masters this year...). Felt good for the intervals this time, increased power a bit each effort. Averaged 109% of what I have my ftp set at currently. I'm liking this effort/rest length - it's long enough to feel like I'm working threshold but short enough to hit > ftp power, not to mention 20 minutes from home so I can fit in a solid workout in 90 minutes.
