Todays effort is going to be a little into the threshold zone, but nothing too crazy. Broken up into rounds even with some building built in, all in all a very tame workout in that FTP effort. Warm up 7min super easy and then 10min of 1min build to fast RPMs into 1min easy RPM. 5min easy into 2 rounds of 4x2min building from to threshold effort (80-100% FTP build) then 2nd round straight at Threshold with 2min between.
