Your anaerobic threshold, is 84-90% of your maximum heart rate, not your red zone, Zone 6 94-100% of your heart rate would the red zone and you only last very very short periods, 2-3 seconds in this zone, the red zone. Maybe change to riding in your anaerobic threshold zone..
Depends on who you talk to. I understand anything over anaerobic threshold is usually called the red zone (as you say anything over 84-90%).
Is it possible to ride between 90-100% for a sustained period? I don't reckon I could do it all the way up the Longley-Neika climb but that's the challenge isn't it. Take a look at the Strava results of some of the riders in the Wellington TTT (e.g. . Some of them ride at (I'm guessing a bit here) over 90% max HR for 30 minutes. I don't know how they do it.
