I'm not Caskbill, but I always run a bit when I'm at WDW, and I've measured the routes with a GPS (geek), so here goes:
From the entrance to the landing dock at MGM to the spot where the bridge to Swan/Dolphin meets the walkway (behind Jellyrolls) is 0.76 miles. I suspect the entrance to MGM is very close to the same distance.
One loop around cresent lake is 0.80 miles, and I'd guess the distance from the walkway/bridge spot to the Beach Club is about 40% of that, say 0.32 miles.
