I want to try this for the exact reason you pointed out. I think it would also be more fun to go fast for a shorter period.
For me, there is nothing fun about it. It feels awful during the sprints, and it feels somehow worse when you stop. I feel like shit for a good 15-20 minutes after I'm done...Not a tired but satisfying feeling...just awful. It really works, though.
