Course 1 was given as 7.5km and was interesting in that the first 5km was a back and forth tour around the main map with the last third of the course taking us out and back on the surrounding street map with only two controls. After a couple of legs to get us from the start onto the mountain proper, a number of short legs tested our fine navigation skills and the strength of our legs as we ran to the top of the hill, dropped down the other side and then returned most of the way back up to control 10. The route choice on the legs to 8 and 9 are worth mentioning as they both gave the choice of bashing through a fairly large thicket directly to the control or running a much longer distance around it. I took the outside route to 8, passing to the west of the thicket as I couldn't be certain of my exit spot if I ran through but I crashed through the thicket, taking advantage of old tracks where possible, on my way to 9 as I knew that I would come out onto the track at the south edge of the thicket at some point and could then follow that directly to the control. This seems to have been the best approach.
Exiting the mountain, we had a few controls in small reserves on the western side of the map before returning to the shopping centre area for a number of controls in the building detail. One or two of the controls were probably not exactly where they were mapped - control 17 was affected by construction work on the nearby building and appeared to be on the wrong tree - but all were easily visible once you navigated to the centre of the circle.
The last loop on the surrounding streets map had looked to be an add-on that just made up the distance but in fact all three legs offered route choice and, comparing notes afterwards, Jonty and I differed on our route choice on the first two and agreed on the final one. For the leg to 22 I stayed on the roads all the way while Jonty took the internal tracks back past the start / finish area; to 23 I went east while he went west and for the final 1100m leg to the finish we both ran the roads down to the cul-de-sac that allowed us to approach the finish from the south-west. We crossed paths a couple of times during the race and it would appear that I gained most if not all of my one minute advantage on that last leg.
