What a really nice post just about sums up tomorrow thank you West of Anglesey: Ynys Cybi- Holy Island it’s greatly appreciated from all the team😃🥰👍

Regarded as one of the UKs toughest marathons, the Cybi Coastal Marathon takes place this Saturday 1 August with almost 600 runners due to take part in the two races - the full course and the C25K (half marathon) .

Starting & finishing at Holyhead RNLI Lifeboat Station , this circumnavigation of Ynys Cybi – Holy Island – is at 26.2 miles, a natural marathon distance loop. The route largely follows the Anglesey Coastal Path covering a variety of terrain - paths, tracks, beaches, including tricky cliff tops , and a short sharp climb to the top of Holyhead Mountain – Mynydd Twr and back down to sea level.

400 runners have signed up for the marathon which starts at 09:00. There’s also a half marathon C25K which starts at 10:00 & new for this year, a “Kids Fun Run” around the Newry Promenade starting once the other runners have departed.

Organised by three locals – Andy Williams, James Harper and Kristian Cuffin – it’s a "not for profit" event, raising funds for the local RNLI stations whilst striving to be as sustainable as possible.

To all the runners, organisers , volunteers and marshals - Good Luck – Pob Lwc! 👏

⛰️🏃‍♀️ T-MINUS 2 days 🏃🏻‍♂️ ⛰️

In just over 48 hours, 600 of you will embark on the worlds best marathon (in our opinion 😉)…

Registration opens from 7:30am, so for those that need to collect bibs please make your may over. Remember marathon race kicks off at 9am and C25K at 10am so try to come with enough time to spare and to answer any questions you might have.

Few questions we always get;

are the checkpoints loaded with food and drink? Yes, water and sugary snacks will be available.

Can we use poles? Of course, no rules against not using them.

Can supporters access the route? Yes, it’s all coastal and public footpath and easily accessible.

What is the cut off? A generous 9 hours for marathon and 8 hours for 25k

We really are looking forward to welcoming you all again for what will be our third year together as a team and event 😄
