6x4 vo2 intervals. 345, 337, 320, 322, 314 (ouch!), 322. I wasn't doing them by power, my coach said to go as hard as I could for 4 minutes. According to wko my vo2 zone 286-326 so overall not bad...
That's crazy. If I ever had a coach tell me to do multiple intervals as hard as I can, I'd have to sit him down for a talk. So, did you set a 4' power record on the first one?
