I'll be doing it,
I've done a few both crc ones and when Merida did them, they are usually very well sign posted, a few marshalls about at sections where dif distances split. So very easy to follow,
There has always been hundreds doing them along with the number plates so you'll see someone to follow,
I don't live to far away and unless we get some tropical down pour it will be very dry, Unlikely to cause any brake pad issues.
I'm doing the 50k with a couple of others if anyone wants to tag along.
