Carl Mowatt, 56, manager of the Lakeside Inn pub in Jarrow, will take on the Montane Cheviot Goat Winter Ultra Run to raise money for Myeloma UK, in tribute to his brother in law, Mark Maitland, who suffers from the disease.
The route, which involves 9,500ft of lung-bursting climbs – more than the equivalent of scaling Ben Nevis twice - takes in the highest peaks in The Cheviots, starting and finishing in the village of Ingram.
Carl will climb peak after peak, brave miles of bogs, sub-zero temperatures and have to navigate through wilderness in the darkness to complete the race, which is organised by Cold Brew Events.

The event attracts top runners from around the world, including Jasmin Paris, who claimed first female in 2018 before going on to make global headlines as she smashed the record for The Spine Race, which follows the Pennine Way, in January 2019.
Experienced runner Carl is no stranger to ultramarathons, having previously completed the Sierre Zinal in the Swiss Alps, and The Wall – taking in a 70-mile stretch of the Roman Wall from Carlisle to Newcastle - raising thousands of pounds for various charities in the process.
He said: “I love the fact that I can run and compete in these distances. Having been a keen runner for many years, I had a 17-year lay off before getting back on track in 2017.
“I now run as with South Shields Harriers, along with a second club – Vegan Runners UK - and also receive great support from other local running clubs, in particular Jarrow and Hebburn AC.”
Carl chose to run for Myeloma UK after being touched with how his brother-in-law Mark deals with having the disease. He and is hoping to raise £500 for the charity.
He said: “I have been personally touched with my brother-in-law Mark being a sufferer and battler of Myeloma.”
The Montane Cheviot Winter Ultra Run will take place on December 7, and you can donate to Carl on his Just Giving page.
