I was poking around YouTube, catching up on my various channels that I haven't had a chance to watch in the last couple months, and saw the GCN vid on how long a novice, an enthusiast and a pro could each hold 440w (Wiggin's average power during his hour record). The novice, although a big guy, couldn't manage one minute. Ollie, as the enthusiast, managed a little under 4 minutes - not bad. Watching their pro in disguise was humbling - 46 friggin' minutes. Yow.
