Really? Ok, well your clarification has been noted thenacoggan said:Uh, point of clarification: 20 min at 105% of functional threshold power is a maximal effort for me regardless of whether I'm indoors or outdoors. In fact, I think I'd find it just a tad easier indoors (unless you gave me a steady 4-6% grade and some friends to race against).
My FTP is actually just 90% of my 20 minute power (outdoors).
I do all 'testing', except for all-out sprints, on steady climbs which feels easier for me in terms of steadying my effort.
