The physiological condition which really dictates what ftp is occurs between 45 and 70 minutes. It could be reached at 45 for some folks or held to 70 for some folks. Not specifically 60min. I said 60min in the original topic as the Zwift stuff uses defined w/kg limits based off of concrete times like 5min, 20min, or hour, etc..... So, I chose an hour.
