Route: Welsh Three Peaks (United Kingdom)

Nathan Flear posted the route:

The Welsh Three Peaks Challenge takes in the three peaks of Wales: Snowdon (Yr Wyddfa) in the North, Cadair Idris in mid-Wales, and Pen y Fan in the South.

It includes a total running distance of 17 miles (27.4km) with an ascent of around 1500 metres (4920ft), there is also around 4.5 hours of driving inbetween. 

I'm not sure if anyone out there knows of an existing FKT on this, I have spoken to Three Peaks Challenge UK who register records and they have said they don't know of any particularly notable times.
