Of course an interval a 10x 1min on/off can be done for but it won't be at the same power level and the fatigue will be great. Another variation are "under/overs" where by the power goes slightly higher for 1 min in the oder of 5% of FTP, lower for 1 min etc for 20mins or longer. A "kilo" style effort could not be done repeatedly however.




Well technically speaking "genuine recovery" takes place after proper sleep and nutrition.... but for the purposes of repeating efforts it largely dependant on the individual. The times are arbitrary. There are schools of thought that basing rest on HR, lactate level or time yields the best results, dependant on the adaptation that is wanted.

For the purposes of hitting the required wattage for the 2 x20mins session a 10min rest seems to be around the minimal amount required in order to be able to repeat the second effort at the required wattage, a mental break if nothing else.

Unfortunately for me, I will only be able to get a pm until the end of the year. I will do the same hill this week and I will keep track of the vam with my sigma rox.
The last time I checked with the second climb, it read 14-16% most of the time.
