From the organizer

Organizer's website

Circumnavigating Ynys Cybi on the Welsh national coastal footpath and Anglesey coastal path, Cybi Coastal is hoping to establish itself as one of the most scenic marathons in the UK. With a limit of 200 runners, we hope this event will attract participants from across the UK who will come to compete alongside local runners on this fantastic route.

Cybi Coastal Marathon route

Course Details
The Cybi Coastal will be partially way-marked and will follow the paths, tracks, beaches and coastline of the Welsh national/Anglesey Coastal Path. The entire route passes through magnificent coastline scenery with fine views of wide bays, sandy beaches, dramatic cliffs, the famous South Stack lighthouse and the summit of Holyhead Mountain.

Starting in the port town of Holyhead this race takes you on a variety of surfaces. Easy going paved paths, a small amount of road sections, sandy beaches, fields and single tracks. Tricky cliff tops and with a few good hill climbs and to top it all off a short sharp climb to the top of Holyhead Mountain and back down to sea level. Depending on the weather, this course can be very muddy and trail shoes are highly recommended.

    Down to earth no frills event with a great environmental ethos. The team couldn't do enough to make us feel welcome, and all done for a great charity. The course if stunning even with the mountain in the last few miles. its the little touches like the hose pipe shower on the finish line that make this so special.

    Beautiful scenery, brilliant volunteers and a very friendly atmosphere made this very challenging marathon the most memorable ever! I definitely want to revisit this one!

    Really well organised and a great atmosphere. The scenery was stunning with woods, beaches and a mountain along the coastal trail. It was my first ever marathon and the it was tough in places but a great experience and so many friendly volunteers and runners. An amazing day!

    Great event, well organised with minimal environmental impact in this beautiful area. Tough course but well worth it for the fantastic scenery.

    Did the first and now the second. Looking forward to the third. Great scenery and support around the course. What I call a 'proper' run as it covers terrain you won't get on a boring road marathon.

    Having run this race in both 2018 and 2019, it is a wonderfully friendly race, with stunning scenery. It is carefully organised with core environmental values and raises awareness of critical local businesses and organisations. The course offers challenging trails and elevation, but once conquered is a wonderful confidence boost! Although a tough challenge, it is a friendly race, welcoming to runners of all abilities. However, this is not to say the challenge should be underestimated: the climb and descent in the last few miles will grip you, making this both a tough mental and physical challenge to relish. Can’t wait to sign up again, fingers crossed I’m quick enough to respond to entries opening for 2020!

    Did the Marathon in 2019

    This event is very well organised and set on the beautiful island of Holyhead. The course takes you around the stunning coastline which is rugged and extremely challenging in parts with the final 4 miles having you summit and descend Holyhead mountain.
    I can honestly say I have not seen so many broken people cross the finish line at any other race but all with an overwhelming sense of achievement receiving the very unique finishers medal.
    I would highly recommend this race to anyone who wants to take on a real challenge of a marathon.
    Well done to all the Cybi team and volunteers and I shall definitely be seeing you all again in the future.

    Gorgeous views, challenging course, great check points/food stations, organisers friendly and encouraging, soup, bread and tea at the end - perfect!. Advise to park nearer the event start than we did a mile away! There's actually loads of parking nearby. Really enjoyed my first marathon.
