Planner's Comments:

Results are now available.  The issue turned out to be due to a couple of the control boxes that were used returning a different number to that on the SI box label.  All sorted. 

Shame about the weather, but despite this, there was a good turnout of competitors across the age spectrum.  The format of a 3-leg 1-person relay suits Marden Park very well, which is too small to run normal length line courses in.  The stacked legs with a common Start, map exchange and Finish worked well.  The map tent proved to be useful in keeping the (unused) maps and officials dry.

Leg 2 (144 Stream source) to 3 (136 Reentrant) caused more post event discussion than any other.  There were 3 alternatives:  straight, west around and east around.  The straight route was only 40m, but involved a steep slippery bank with tree roots for hand and foot holds.  West around, 80m, used the deep, but easy angled, reentrant to overcome the slope.  East around was 145m of gently rising contouring.  Which was fastest?  Best direct time was 1:33, best east time 1:23 and best west time .... I don't know.  Andy Ellis had the fastest time and took the contouring route, so I declare this to be the best choice.

One suggestion from the woods was to run the O-LG-Gr course in reverse - the Green leg first, followed by Light Green followed by Orange.  This ensures that the area is not already familiar when you tackle the hardest lap, which would be followed by the technically easier, quick decision legs when you are tired.  Next time.

As always, thanks for coming and hope to see you at Brun Valley and the Parks on 6th March.  Maybe there'll be some of that fast action sprinting to savour!

Thanks to our band of helpers.  You know who you are.
