My son Oscar and I are taking on a low-key challenge to walk 100 miles in support of COAST (Community of Arran Seabed Trust).

The Firth of Clyde was once one of Europe's richest marine ecosystems. After decades of decline, there are encouraging signs that recovery is possible, and COAST is helping to make that recovery story a reality.

As someone with strong personal links to Arran, this is a cause that means a great deal to me. Oscar and I will be walking 100 miles before visiting one of COAST's research vessels to learn more about the charity's work around Arran and the Clyde.

If you're able to support us, every donation, no matter the size, will help COAST continue its research, education and conservation work. Thank you very much for your support.
