I've ran the Yorkshireman several times, it's a great race!

Helpfully, the organisers run guided recces in the weeks leading up to the race. I'd recommend you join them if possible. The navigation isn't difficult but it's easier if you already know the route.

Enjoy!

Thanks John. Yes, I'm hoping to recce parts of the route over the coming months. Got the gpx files for the recce.
