I didn't complete a 100km ultra by my 50th. 80km achieved before 53 years, still working on it...

Sheffield Round Walk Route
Here's a GPX file of the route. It's 500 points long to give a good resolution. I tried cutting below 100 and that was usable, but I'd need 20 to get it onto my 12XL. I suppose that would work as 5 individual routes.
