Team Sheldon’s epic challenge along the Trans Pennine Trail
Mary and Sheldon (her trusty dog) are off on their travels again!
Mary and Sheldon (her trusty dog) are off on their travels again!
From 6 – 14 April 2026, unstoppable duo Mary and Sheldon are attempting to conquer 215 miles between Hornsea and Southport – climbing right over the Pennines in nine days and aiming to raise £30,000 for Dogs for Good along the way.

This is a big challenge for both Mary and Sheldon. Just like their Three Peaks challenge in 2024, they’ll be supported once again by the British Army to complete this tough endurance journey.
We’d like to say a big thank you to the British Army, and our other supporters Škoda and the Trans Pennine Trail, for their support for Mary and Sheldon’s challenge.

Keep a lookout for Mary and Sheldon (and their team of supporters) along the trail and give them a cheer!
