Cardiff Taff Trail Half Marathon 2026

The Cardiff Taff Trail Half Marathon begins at Pontcanna Fields Car Park, directing runners into one of Cardiff’s primary green spaces. This chip-timed half marathon features online entry, an 08:30 start, and race-number collection prior to the start. With a 3-hour cutoff, it is structured as an efficient city race, not an extended trail excursion. The course crosses Pontcanna Fields and Bute Park before proceeding north on the Taff Trail towards Tongwynlais. The majority of the route follows tarmac paths, with a brief compacted section. Aid stations are located at approximately 2.5, 6.25, and 10.25 miles. The event originated as a pilot and resumed post-Covid cancellations, offering Cardiff a smaller Taff Trail half to complement the city's larger October road race.
