Orienteering race 1:23:15  4.8 km (17:21 / km)
Utter utter carnage.
I'm relatively new to navigation.
I found the last "Active" level event I did not that challenging so decided to step up a level of difficultly.
This was the first time I attempted "Expert" level and I *sucked*. It was really hard and I spent literally half and hour wandering around lost. Turns out I'd over-shot substantially. Getting the scale correct on these little ones is hard, as I'm most accustomed to rogaining maps.
But you've got to learn somehow and I'll do it again.
