Undergeared, as in you were running out of gear? Then I'd stick to 40x20 for Ed Sander; maybe bring an 18t or 19t, and leave time to swap after warm-ups. The gravel climb is fairly long and the two (three?) berms before the backside descent are much slower on foot. If it's at all wet, be extra prepared to dismount and run (see comments about Gawdzilla in the video above) - that applies to everybody, but especially to SS where you lack gears to power through thick mud or up the climbs.

Mike - you are correct that the course doesn't loop back on itself. That said, the back-nine area (the muddy run-up) is a fun place to spectate. Plus, they have beer and waffles. Not the best family (w/ kids) venue, but if they aren't doing anything else, and it's a nice day, it's not bad.

Spongedad - shame on you. Cold rain, mud, and more cowbell, please.
