Taking place on Saturday, the 10K lets runners enjoy a fully supported trail race through the stunning landscapes of Eryri (Snowdonia) National Park, all to themselves. After crossing the finish line, stick around in the race village to soak up the atmosphere and cheer on friends and family competing in the Marathon, Half Marathon, and Ultra Marathon the following day. It’s a great way to experience the excitement of the weekend, challenge yourself, and enjoy the trails without the crowds!

The Route
This beautiful 10k has something for all runners. The first 5.5k has a mixture of road, track and trail and takes in the beautiful lower slopes of Yr Wyddfa (Snowdon). It then passes across the valley dipping into the beautiful woodlands around Dolbadarn Castle before taking on the gruelling Zig Zags that take you to the top of Vivian Quarry. Once here it’s down hill on stunning forest trails all the way to the finish line.
Already Have Your Own Place?
If you already have your own place and would like to Run 4 Cancer, we would be delighted!

Email us at Events@4cancer.org and we’ll get in touch right away! Thank you.
Guaranteed Entry
We have a very limited number of subsidised places available. All we ask is that you raise a minimum of £150.00 in sponsorship funds in support of Run 4 Cancer. We set very low minimum sponsorship levels and fully understand that the cost of living crisis is impacting people’s ability to sponsor people.

Run 4 Cancer - About Us
Set up by a team of running enthusiasts, all of whom have lost a family member or a friend to cancer, Run 4 Cancer is primarily a provider of days out and short-breaks for British families affected by cancer. We give families something to look forward to during the most difficult of times. We also make grants to UK based care institutions and support research into the positive effects of exercise (e.g. running) and how it can help with cancer prevention and recovery.
