M10 Cardiff

Welcome to the inaugural M10 Cardiff race series for 2027, joining Swansea and Llanelli as part of South Wales' premier racing circuit. This exciting addition offers runners an opportunity to test their mettle across diverse terrains within Bute Park and along the scenic Taff Trail.
On January 17, 2027, both the 10-mile and 5-mile races will start at Coopers Field in Bute Park, with participants navigating a full lap around the park before venturing onto the trail. The event is meticulously organized to cater to runners of all abilities, from seasoned competitors chasing personal bests to those simply enjoying the day.
Registration opens early for an efficient morning setup, starting at 07:30 AM and closing promptly at 08:45 AM. Briefings are scheduled just before each race start time—08:50 AM for the 10-mile run and 09:05 AM for the 5-mile event—with both races kicking off moments later.
The M10 Series Championship adds an extra layer of excitement, rewarding top performers at the season's end. Event facilities include chip timing, fully marked routes with marshals, water stations, and a finisher’s medal to commemorate your achievement.
Participants will appreciate the scenic beauty around Bute Park and along the Taff Trail as they race through this historic setting. The event is sanctioned by Welsh Athletics, ensuring adherence to strict rules including no headphone use for safety reasons.
Join us on January 17th in Cardiff for an unforgettable running experience that celebrates the spirit of competition and community.
