Thanks Llani Boy, it was indeed me.
The heat was attritional - trying to cope with that while exerting enough to get through the cutoffs was key.
I'm impressed with the thought that has gone into planning the route - they could easily have taken the race on a lot of roads but instead found seldom-used paths and small back lanes for much of it.
Congratulations on finishing Bill, 18th overall and 1st M55.
