Hang on to wheels and you'll be ok, but lose a wheel and it's one of those courses where the group will disappear fast!I think that's the bridge, hairpins and the two small bumps that I've mentioned combined. With A cat speed I could see how someone would see it as one. For me, it's more like a 1 min effort (bridge+hairpins), 30s rest (flat/rolling), 15s effort (1st bump), 15s rest (flat), 15s effort (2nd bump) and then put down some power before a supertuck.
Not a hard course in the climbs, but very little rest, if any at all. You'll be on the pedals pretty much all the way .... you may get 10-15 seconds of supertuck on the way to the finish line, but not much more.
