I have found that there is a lot of flexibility in training programs. For example, one can to 2 sets of (4 to 6) 90 second anaerobic efforts with 5 minutes rest between each interval and 10 minutes between each set. I might do 4 intervals on the the first set and maybe only 3 on the second or maybe all 6 depending how I feel. Some days the chain is gone and other days it feels like a gorilla jumped on my back.

I do not know if you have a power meter but the power manager in WKO is great for managing training stress. It can also be done with Trimp scores for heart rate. Good luck and have a great season.
