What is it?
Rogaines are navigational contests with a fixed time limit for teams on foot.
"Big" means it's bigger than our regular after-work rogaines and "Trig" means there are some hills!
There will be a 1hr rogaine, a 2hr, 3hr, 4hr and a 5hr rogaine, with good gaps between. You can choose one or more, with a premium competition for teams which do them all.
You can also choose a 15hr "adventure rogaine" with three rogaines joined together by mountain-biking.
