Well it was a bit claggy in places which made the route finding a bit more fun.
Many thanks to the organisers and all the marshalls for putting on an excellent race. A query for others though:
I was recording the route on Viewranger on my phone (locked away in my bumbag before anyone asks! I was using my map printout and trusty thumb compass to navigate). I took pretty much the optimum line but have recorded ~1500m of climb which is a fair bit more than the advertised 1220m. A quick check of the map shows that 1500m is more likely than 1200m so I was wondering if anyone else had recorded their climb stats?
