Ross Jenkin will attempt the four challenges in a continuous round

There must be something in the water this June as another endurance athlete sets out on a quest to set a record.

Ross Jenkin will begin his Big Four Grand Round challenge on Sunday.

He will attempt a continuous round of national 24-hour mountain challenges in Scotland, Northern Ireland, Wales and England. It is believed the feat has never before been achieved.

Starting with the Ramsay Round in Scotland, then the Dennis Rankin Round in Northern Ireland, next the Paddy Buckley Round in North Wales, and finishing with the Bob Graham Round in the Lake District, the runner will attempt a total of 152 summits, over 387km (240 miles) with 31,800m (104,330ft) of ascent.

Jenkin attempted the challenge last August but was thwarted by injury and Storm Francis. The Dynafit-sponsored athlete is raising funds for the Campaign Against Living Miserably.

He said: “Turning 40, a mid-life crisis of sorts, this is a challenge I can’t get out of my head. Plus, I want to raise money for a cause which means a lot to me. I suffer from depression so encouraging others to do something which helps their own mental health and promotes talking about your problems.”

So far, he has raised more than £6,000 and is aiming for £15,000. As he says, “The power of the mind is immense. I can safely say that I am stronger now than I was before all this. Don’t man-up, speak-up.”

He plans to rest only on the travel legs in between the rounds.
