TR has a session that goes something like this,
Warm up
3 mins at 110%
3 mins recovery
3 mins at 120%
3 mins recovery
3 mins at 130%
8 mins recovery
3 mins at 130%
3 mins recovery
3 mins at 120%
3 mins recovery
3 mins at 110%
Recovery.
I find it utterly brutal. If my FTP is accurate and I'm feeling good I can just about handle it. The 2nd 120% is the killer as I'm usually spent after the 2nd 130.
