Cardiff (Cardiff Daily) October 3, 2026 – More than 29,000 runners will descend on the Welsh capital this Sunday for the 2026 Cardiff Half Marathon, traversing a 13.1-mile course showcasing some of the city’s most prominent landmarks while drawing international elite athletes and inspiring local fundraisers alike.

Why is entry to the Cardiff Half Marathon by ballot for the first time?

Due to the event’s growing popularity and surging demand, entry to the race was balloted for the first time this year. As reported by Andrew Richards of BBC Sport Wales, more than 60,000 people entered the ballot, and the lucky winners secured their spots to race through the city on the same course as the world’s best runners.

As reported by Andrew Richards of BBC Sport Wales, Run 4 Wales chief executive Matt Newman stated that

“I think it’s absolutely reinforced the popularity”.

Furthermore, Newman added that

“It’s a vote of confidence from runners who’ve run it and want to come back every year, and then there’s an emerging market of younger runners who want to do it for the first time”.

He also acknowledged that

“It has also disappointed quite a few people in terms of not being able to take part on Sunday, and we’re conscious of that as well”.

This year’s participants range in age from 17 to 85, with 91 runners celebrating their birthday on race day. Elite athletes aim to finish the course in 60 minutes, while many hope they still retain enough energy by the time they reach Roath Park.

How did Louis Price overcome heart surgery to run the half marathon?

Louis Price from Aberdare was born with a heart murmur, but that did not stop him from enjoying sports growing up. At 16, more severe chest tightness led him to give up rugby and football and meant his heart required regular monitoring.

As reported by Andrew Richards of BBC Sport Wales, Price, now 25, explained that

“In January 2025, one of the scans came back, and it was deteriorating a little bit”.

Price added that

“I then went in and had the open-heart surgery, and unicuspid aortic valve was the official diagnosis in the end”.

A unicuspid aortic valve is a rare congenital heart defect where the valve features only one leaflet instead of the normal three.

As reported by Andrew Richards of BBC Sport Wales, Price stated that

“I wanted to raise money for British Heart Foundation, raise a bit of awareness for younger people who have heart defects”.

Price further commented that

“I didn’t think I’d be running the Cardiff Half 12 months ago. I wanted to push myself, but I didn’t know what that what that would look like”,

concluding that

“Being able to actually do it, I’m really looking forward to it, and it’s quite cool”.

What inspired Kiera Hodges to run for her local hospital?

Kiera Hodges was just 14 when she was diagnosed with acute lymphoblastic leukaemia in 2020. She spent the better part of two years at Noah’s Ark Children’s Hospital for Wales in Cardiff and is now an outpatient, having rung the bell three years ago. At 21, Hodges studies biology at the University of Bath and recently returned from Malawi after spending her placement year helping with bat conservation.

As reported by Andrew Richards of BBC Sport Wales, Hodges said that “I have a lot to give back to the hospital”. She added that

“I always love to push myself, and doing it in Cardiff just feels extra special”.

Hodges explained,

“I grew up here, the treatment was here, the hospital is here, so it’s really special”,

before noting regarding her post-race plans that

“I have to go straight back to Bath afterwards. We are stopping off at my friend’s house, and I think we’re having a cottage pie, so I’m very excited for that”.

Why is Sam Jordan running for Tŷ Hafan?

At three months old, Sam Jordan’s daughter Liwsi was diagnosed with two rare genetic diseases, Cri du Chat syndrome and an Xq28 duplication translocation. He wants to give back to Tŷ Hafan, who he says have been there for Liwsi as well as himself, his partner Zoe, and Liwsi’s older sister Alys from day one.

As reported by Andrew Richards of BBC Sport Wales, Jordan said that “I guess it’s emotional support”. He elaborated,

“We live in a day and age where men can’t speak about their feelings and ongoing issues, but luckily enough, Tŷ Hafan have provided us with a couple of support workers who I’ve been able to open up to a bit”.

Speaking of his daughter, Jordan noted that

“Liwsi has no idea what’s going on, but she’ll be there supporting”,

adding that

“And I know that when I see her, she’ll be smiling. She is the happiest little girl you’ll ever meet, so what more motivation do I need?”.

How has former Wales rugby star Adam Jones prepared for the race?

Adam Jones is one of Welsh rugby’s most recognisable cult heroes, boasting a glittering career as a three-time Grand Slam champion (2005, 2008, 2012) and a British and Irish Lions series winner who earned 100 international appearances at prop before retiring in 2018. Now aged 45, the Harlequins scrum coach has lost more than five stone (32kg) after starting his fitness quest using a couch-to-5k approach.

As reported by Andrew Richards of BBC Sport Wales, Jones stated that

“When I was out in Japan with Wales last year, I remember the camera panning to me at the end of the tour, and I was massive”

. Jones added that

“I thought I needed to do something about this”,

and noted,

“As soon as I started doing it, I saw the benefit of the process. It was fascinating to see and develop week-to-week”.

Running in aid of two charities, St David’s Hospice Care and Prostate Cymru, Jones joked about his race strategy, saying that

“I might go incognito in the race so no one can see how slow I’m going”.

He quipped,

“Maybe I’ll put a balaclava or a daffodil hat on, so I don’t get abused!”,

but added that

“I’ve heard good things about the event and how people support you. I’m hoping the Welsh public will get me around the last few miles”.

What is the route and weather forecast for race day?

The 13.1-mile course starts outside Cardiff Castle and takes runners past both Principality Stadium and Cardiff City Stadium on the way to Penarth. The route then leads from Penarth Marina over the barrage in Cardiff Bay, passing the Senedd building and the Wales Millennium Centre. After a loop of Roath Park, the race culminates outside the Civic Centre.

Organisers have advised participants to allow plenty of time to get into the city centre ahead of the 10:00 start time, with several road closures in place across Cardiff. Weather conditions look optimal for both running and spectating, with sunny intervals and a gentle breeze forecast.

Who are the elite contenders aiming for course records?

Former world record holder Joyciline Jepkosgei headlines the women’s elite entrants, while the fastest man in the field is fellow Kenyan Gideon Kiprotich. Jepkosgei was the first woman to run the half marathon distance in under 65 minutes and boasts victories at the 2019 New York Marathon and 2021 London Marathon. Kiprotich, winner of last year’s Rome Half Marathon, will become the first sub-59-minute runner to line up in the Welsh capital. He and returning champion Yismaw Dillu of Ethiopia will attempt to challenge Dillu’s course record of 59:23.

Background of the development

The Cardiff Half Marathon has evolved significantly since its inception in 2003, expanding from a modest local race into one of the United Kingdom’s premier mass-participation running events. Run under the umbrella of Run 4 Wales, the event has consistently drawn tens of thousands of participants, contributing millions of pounds to charitable causes while boosting the local economy through sports tourism. Over the years, the integration of high-profile elite athletes and heartwarming community participation stories has cemented its status as a major fixture in the international running calendar, culminating in the introduction of an entry ballot for the 2026 edition due to unprecedented global demand.

This major surge in participation and international elite interest is expected to heavily benefit the local economy of Cardiff, generating substantial revenue for hospitality, transport, and retail sectors across the Welsh capital. For the local community and aspiring runners, the widespread media coverage of inspiring human-interest stories—such as participants overcoming open-heart surgery, cancer survival, and significant weight loss—serves as a powerful catalyst for public health engagement, encouraging higher localized rates of physical activity and charitable fundraising. Furthermore, stringent logistical measures and road closures required for the event will test city infrastructure, prompting ongoing adjustments by municipal planners to accommodate future large-scale gatherings safely.
