You were doing EXCELLENT! Until you blew 17 minutes on the fifth leg. But up until then, you were placing 3rd or 4th on each leg. You must have been in oxygen debt from the effort. And lost concentration. You can make it up tomorrow. Good luck!
By the splits it was no 10 in an area where you had 20 seconds at the start to check the trail changes on the map???
I would if never remembered or even recognized the area at the time.
I was just messed up that’s all.
