It is an interesting concept...
Bu I cannot stop thinking at the way climber like and Steve House and Ed Viestur trains today, and people like Hermann Buhl trained yesterday.
If it is true that training is adaptation of your body to the activity that you will be performing in the game, and I guess here we are talking about climbing, short intervals only will not prepare you for the long and sustained effort on the mountain.
Alpine climbing is a different game from many other athletic performances, it requires burst of more that few minutes of pure strength and hours long endurance efforts, all of this several times during the day for multiple days with minimal rest.
So I believe the body needs to develop adaptation to these factors with long endurance session and short intervals training.
Maybe I am little old school but when i heard at a conference that Ed Viestur bikes and run between 6 and 8 hours in a day for training that tells me with the results he had that maybe I ma on the right track....
Anyway I will go today for my 18 miles run with 27 degrees outside....
