A blank map was given out to carry around face down on our map boards to act as a safety net, in-case we lost the plot, but essentially there was a 2 leg little bit of laminated map hanging from a tree at each control and you had to memorise your route.
To be honest as we had been there in the morning and as we wound our way round again it was also a bit of terrain memory but excellent all the same. I tried 4 times to remember double legs, ie not stopping for two controls and memorizing the route the whole way. I managed it twice and had to resort to the backup map close to the control on two occasions to finish the leg.
The area is crisscrossed by dedicated MTB singletracks and we had a great time too enjoying these outside of race conditions before heading back to base before heading out for a team meal.
