hahaha what happened there!!
I'd like to know the answer to that. This is what I think happened:
Left control, because it was fairly far in from the track, decided to crash through to the other side of the loop of path (which now seems dumb even if perfectly executed). I guess that we turned while we did that and went parallel to the path, then back onto the path we had just left where we turned the wrong way (now 180 degrees out) and ran back almost all the way to the control where Alexa finally twigged that we were on the original track (should have recognised at least the path junction - I did the 3rd time we went past it...)
After 30 years I thought you'd have worked out that the sun is in the north down there ;-)
I think the sun had gone down about 70 minutes earlier - we got 30 minutes from the start before we had to put out lights on.
Ah, well that plastic thing you carry in your hand has a red pointy thing which points north. Do I get my coaches badge?
When I complete a whole night of rogaining without a missed cake, THEN you get your badge
