Formally known as the Snowdonia Marathon, Marathon Eryri on 25 October 2025 is on a demanding and spectacular route which encircles Yr Wyddfa – the highest peak in Wales. It's one of the hardest marathons in the UK.

I've ran this before, and it's tough. Wet, cold, muddy, hilly, sleet, rainbows - it has it all. I'm hoping to complete it before the 5 hour point, but at a push I'd really like to get 4.45 hours. It's 26 miles, but with all the inclines and hills, it actually is closer to 30 miles. It's bleeming hard!

The charity Tenovus supports those with cancer, and over the years I've raised thousands for this worthwhile cause. Please help me get to my target.
