Seriously looking at the map here... Marked the checkpoints for the 37 mile route according to the website, but there seems to be a dazzling array of route choices.

Looks like the potential's there to go well and truly wrong

I'll probably just take the plunge and keep an eye on the map and who's in front of me....and there'll be plenty of those!

I'll trawl through the old posts to aid map marking and route choices.... Taking into account the fact the route alters...

Who else is likely to be there?
