You dont need any support to do it on your own..

Just get drive up the route, leave some drop backs.. drive back to Milngavie.. run out.. train back..

There are plenty of shops enroute.. plus drop bags..

If you want to do it that way. Over 2 days would be more pleasant stopping in a hostel.

I would rather a supported race, but the WHW is unique in its family atmosphere, well from the ones I've done but the sport is ever changing.. I've not done any of the hardmoors series so dont know how they compare..

But I do think it adds to the atmosphere.. but there is a stress of being dependant on people so I'd be worried about relying on strangers.
