Fully recovered from chest cold and back to 100%. Knew this was going to be “fun” - dialed down to 115% and then 110%. Still not enough - turned each 3 min interval into two 1.5 min intervals, so this went from Spencer +2 6x3min to something entirely different at 12x1.5min. C’est la vie 
VO2max work is hard for me, and is both a weakness and a limiter. Two years ago I worked hard on vo2max and got up to 5-7 minutes at ~108% and it felt great! Right now I have no problem doing 30-60 sec vo2max/anaerobic intervals, but the wheels start coming off above 90 sec.
The plan? Finish up SSB2 and in two weeks I’m going to do a Coach Chad VO2Max Boost block before starting Build. At a minimum I need to get to 3min at 110% before proceeding with Build.
