I'm about to start the ZA workout #10 so if anyone bumps into me during the ride - it will explain why my speed goes up and down so erratically. Looks a tough one to me, soon find out.
Yep, that was hard.
Main part was 7 x 5 minute pyramid intervals 4-1, 3-2, 2-3, 1-4, 3-2, 2-3, 1-4 115%-88% of FTP with 3 minute recovery in between.
I made it all other than the 3 min 115% segment on the 5th block - where I managed 90 secs only.
Still, that is all the workouts done. Just 1 group ride to go.
