The Denis Rankin Round is a mountain challenge which connects all the 400 metre plus summits in the Mourne Mountains, County Down, Northern Ireland.
The distance is around 90 kms (56 miles) over 39 tops with a total ascent over 6000 metres (20,000ft). As a rule of thumb each top included has at least 30 metres ascent and descent from neighbours, although there are a few borderline cases which have been deemed worthy of inclusion. The circuit can be done either clockwise or anti clockwise starting from the white arch at the entrance to Donard car park, Newcastle. The summits must be done in the order stipulated and the challenge is to complete the circuit within 24 hours.
I had attempted a Denis Rankin round last autumn, but I lost.
