After an august thru mid-november of virtually 0 miles, i've been sporadically riding base since the end of november through now. The with the last 4 weeks or so, I finally was able to workout steadily, and, I thought, had found my legs. All of this was basically SST or recovery.
Last night, I decided to try some 5x5' VO2Max intervals. My target was 115%; first interval I made it fine (well, it hurt, of course) at 116%. Recover for 5', then my second interval - I made it through 3', which turned out to be at 114%, but those last 30" I just couldn't turn the pedals. I had no power, and yes, I wussied out. But the thing is, my legs weren't actually spent, because I was able to recover for another 5', then do 5' @ 101%. THEN I felt spent...with cool-down, total workout was 40'...ugh...
So I have a few questions. First, since this is my first attempt at these intervals, is it reasonable to expect my body just isn't used to these efforts, and so the RPE is much higher than it should be? My second question is - this reallllllly pisses me off. I want to try these again as soon as possible (especially since I have races starting in March..), but I don't want to be stupid about it. What's the most times a week it's OK to do VO2Max work? I need some recovery, but I feel like I'd want to try them again tomorrow morning..
Do I just not worry about it for this week, HTFU, keep steady, and try them again mid next week?
