I was trying to do 4 x 5m VO2Max intervals, target 230-260w (based on my spring era 217-248w goal range, added 12-13w). I was struggling to hold 250w, and most of my efforts were in the 235w range. On the fourth one I pretty much gave up, recovered for about 30 seconds, then did (because I was on Zwift) a "hard" effort to the KOM line. Ended up doing about 400-425w for 40? seconds. My average for the 5m was 234w. My other intervals were 236w (eased for a bit then kept going), 238w (ditto), and 252w (went all the way).
Question is if I do a 400w effort at the end of the 5 minutes, am I defeating the purpose of the VO2 Max interval?
