It shouldn't be a problem MG. I've always managed to find people to follow on The Hebden. It's always popular, and being LDWA, there's always a walker coming up behind you no matter how much you slow down.
In fact, this is the only event in which, whilst attempting to keep running, I've been overtaken by a walker ON A DOWNHILL SECTION!
Just make sure that you latch onto someone who's doing the long course when you're at the major refreshment stop before the short and long routes diverge. You don't want to see your routefinder heading off along the canal leaving you to set off up Stoodley Pike by yourself.
I suspect there might be a few of us who could form a nice little forum group to jog/limp round. The entry list is stuffed with forum celebrities...
