Indeed.
The people at the front of a LDWA Challenge event are runners, not walkers and they'll still be running after 25-30-35-50 miles - and then again the following weekend.
And every year around 500 "walkers" start the annual 100 mile event which might be in Scotland or anywhere finishing in something over 24 hours. And they don't have anyone carrying their kit and mopping their brows and navigating for them. A few years ago at the Welsh Valleys 100 (which wasn't all in the valleys!) one man finished the 100 and then went round again to do a double 100.
Billy said the BGR is only a long walk but for a LDWA member it's not really long at all.
