Orienteering race 1:19:07 [4] 3.9 mi (20:17 / mi)
Red course at Straight Lake State Park in WI. The terrain was fantastic for orienteering, with lots of complex contours and minimal trails.
The distance is a wild guess, because even though I have a fancy new Garmin watch to use for this purpose, the watch spent the race in my car. Hopefully, I'll remember it for tomorrow's Score-O!
EDIT: Re-guesstimated the distance, after comparing my route to iriharding's GPS track. It should be fairly accurate.
