Join Team Tenovus Cancer Care - the Official Charity partner of Marathon Eryri
Marathon Eryri has been voted Best British Marathon twice. The demanding and spectacular route, encircling Wales’ highest peak, gives the event a unique place in the annual marathon calendar.
The 2026 race will take place on 24 October 2026 and if you want to be among the thousands of runners crossing the finish line, sign up with us to guarantee your place.
Charity Place
To become one of Tenovus Cancer Care's charity place runners you'll need to pay a registration of £50 and pledge to raise a target of £350 sponsorship. Our helpful and professional fundraising team will be there to support you the whole way.
Registration opens in December 2025
Ballot Place / Own Place
If you are lucky enough to secure your own place in Marathon Eryri directly, but still want to support us, just join Team Tenovus as an own place runner.
You'll receive the same support as our charity place runners, but there's no minimum fundraising target. Meaning you can select a target that's right for you.
If you have any questions about the event, fundraising or the charities services please get in touch with our team on fundraising@tenovuscancercare.org.uk and a member of our team will get back to you in 2-3 working days.
