From John Hamer after a recent NAV4 training course. He had recently completed the Highlander Mountain Marathon. Video on the site or here
"Hi guys, I'm just back from the Highlander MM. Had a fantastic time, and learned heaps (mostly what not to do next time!) The course was tougher than I expected, with some decidedly tricky checkpoints. Finding a "safe" descent from the top of a 70m cliff is not easy! The organisers also seem to think it's funny to occasionally hide a checkpoint kite behind rocks. We made a couple of minor mistakes, one terrible one (costing us about 45 minutes of painful backtracking!), but had a success here and there. Most importantly, we finished! Thanks heaps, Stu. Your skills course made a huge difference, can't imagine how I could have done the event without it."
A great reply and good to hear some of the magic has worked. Thank you very much John
