All going well - Started on Wk 3 and have completed all rides to plan… Until today! Wk 7 day 4 = 90 mins with last 30 mins involving 4x5mins at FTP with 2 mins rest. Managed the first 5 mins but that was it - HR maxing out, could not hold a decent cadence.
So what to do for the best? Should I re-do Wk 7, back class further to Week 6?, have a couple of days rest and repeat Wk 7 Day 4?? Carry on regardless.
Any advice appreciated.
