I didn't see anything in the bulletin or on the website about the time of day of the sprint relay on Monday 9/19.
Just looking for a rough idea for planning purposes--my partner in crime (a.k.a. fiancee) can hang around for the relay (and be available to the organizers as a helper) if we can be on the road by midday or early afternoon, but if it's going to go much at all into the afternoon, she'll head back Sunday night and I'll be begging for a ride Monday.
Relay start will be at 11:00 am. The arena in Mtn Lakes is great for spectating; hope your fiancee can stick around. Relay will consist of two legs, two km each. The woods are fast, so it shouldn't take more than an hour total, and that should get you on the road by early afternoon.
