The Wales Marathon – Official Guinness World Record Attempt

On Sunday 7th July 2019, the Cancer Research Wales team will be running The Wales Marathon in an attempt to break a Guinness World Record – ‘the most runners linked to complete a marathon’.

The idea stemmed from Cancer Research Wales supporter Neal Gardner, who initially broke the record 10 years ago, when he and 29 other runners completed the London Marathon. He now aims to re-break the record whilst raising funds and awareness for Cancer Research Wales. However, the bar has been raised…

The new record stands at 112 runners, which is held by a team in Canada. We are therefore looking to beat this amazing record, with 120 runners (or more) completing The Wales Marathon, held in Tenby, Pembrokeshire.

How will we be linked together? And what are the rules?

Each member of the team will have a rope bungee (or similar) tied around their waist, linking them to their team-mates. Each runner who starts the race, must complete the race (26 miles 385 yards), and the link cannot be broken at any time.

You can see a short video of the current record holders here.


Each runner must pay for their race entry, at a discounted rate of £25. We then ask each runner to raise a minimum of £500 in sponsorship. The fundraising team will be here to support you with this challenge, providing you with lots of ideas and tips.

This epic challenge will raise a huge sum for the charity, with all funds raised guaranteed to be spent here in Wales, supporting groundbreaking cancer research projects. 

Who will I be running with?

The team will be made of Cancer Research Wales supporters, all giving up their time and energy to support our ground-breaking cancer projects, which are happening here in Wales.

So far, we have a confirmed team from Royal Mail, who, among many reasons will be running in support of their admired colleague Pip, who is currently battling cancer.  If you are part of Royal Mail and would like to discuss this opportunity, please contact the fundraising team on the details below.

We will also have Welsh celebrities running with us, which we will reveal in the build up to the event. The first to announce is BAFTA and multi award winning television presenter, Lowri Morgan. Lowri is also a world-class Ultra endurance marathon runner, having raced in some of the most extreme races in the World. She will be joined by former World champion boxer, Lee Selby.


Will I hold my own Guinness World Record?

Yes, should we beat the record then you will be issued with your own framed certificate, to confirm your involvement in the Guinness World Record. We will also be greeted by the Guinness World Record team at the finish line.

Where can I find out more about the race?

The race is organised by Activity Wales Events. All details on The Wales Marathon can be found here.
