Assume that you are going to be going on a long/hard ride at kind of 'the top end' of your ability (not past it). And it is a hilly ride with multiple long (several miles) climbs. Where do folks tend to ride vs. their ftp (like 100% or 90% or whatever).

Just curious. I don't have any continuous/long climbs in my area, so I have no data/experience to offer here.

Thanks.
