More than 10,000 people are set to take to the streets of Cardiff this weekend as the Kidney Wales CDF 10K celebrates its 40th anniversary.
The event returns to the Welsh capital on Sunday 6 September 2026 and has been expanded to mark the milestone, making this year’s event its biggest yet.
More than 10,000 people have registered across the 10K and 2K races, with entries now closed and no registrations available on the day.
Kidney Wales, which played a part in founding the event in 1986, has become the headline partner and lead charity for this year’s race to celebrate its origins.
The 2K race will get underway at 9.15am, followed by the 10K at 10am. Both races will start and finish on King Edward VII Avenue, with the event village based on the City Hall Lawns.
The 10K route will take runners on a tour of the Welsh capital, passing landmarks including Cardiff Castle, Central Square and the Principality Stadium.
Participants will travel through the heart of the city centre before crossing the River Taff and heading towards Pontcanna and the Grade II-listed parkland of Llandaff and Pontcanna Fields.
Runners will then pass Sophia Gardens, the home of Welsh cricket, before heading past Cardiff Castle for a second time and towards the finish in the Civic Centre.
A 2K race will take place before the main event, giving runners of different ages and abilities, along with their families, an opportunity to take part in the anniversary celebrations.
Thousands of spectators are also expected to line the route, with musical entertainment from The Rock Choir, Just Cheese, Sax for Fun and Super Choir. Performers will embrace the event’s 40th anniversary with a selection of 1980s music.
Kidney Wales will have a team of 280 runners fundraising to support patients affected by kidney disease across Wales.
There will also be a Team Challenge involving 20 teams from companies including Team Vista, Sony and Lab 22, with the latter bringing a team of 130 runners.
A strong elite field has been assembled for the anniversary race.
Almi Nerurkar, with a time of 32:43, and Jenny Long, nee Nesbitt, with 32:19, are the leading entries in the women’s field. Olivia Tsim, who has a time of 33:57, returns to racing post-partum and will be joined by Anna Domville, who has recorded 33:59.
In the men’s field, Sam Tyas, with a time of 29:22, and Welshman Dan Nash, with 29:23, will be joined by another six athletes with sub-30-minute form. They include Felix McGrath, winner of the Speedway 10K earlier this year.
The 2025 wheelchair race winner Owain Terrell, who recorded 30:12, will also return.
Every 10K runner who crosses the finish line will receive a commemorative medal and event T-shirt. This year’s designs feature a retro theme celebrating the race’s 40-year history.
The medal will also form the final part of a matching set from the 2026 Run 4 Wales 10K Series, which has included the ABP Newport 10K, Barry Island 10K and Porthcawl 10K.
