Caernarfon Half Marathon

About the event

Set against the backdrop of Caernarfon Castle, one of Wales' most iconic landmarks, the Caernarfon Half Marathon offers runners an unforgettable blend of history and scenic beauty. Scheduled for September 5th, this half marathon starts and finishes next to the historic castle walls, providing a majestic setting that sets the tone for the race.
The course itself is known for its varied terrain, featuring several small ascents interspersed with long stretches of fast downhill runs. This mix challenges runners while also rewarding them with stunning views of Caernarfon’s picturesque landscape and coastline.
Organizers pride themselves on offering a fair entry fee by matching or undercutting competitors' pricing to ensure affordability without compromising quality. All participants receive a high-quality bespoke medal and technical t-shirt upon completion, celebrating their achievement in style.
Race day begins at 8:00 AM with the race HQ opening next to the start/finish line in front of Caernarfon Castle. Runners must be prepared for strict time limits, as those who cannot maintain an average pace below 15 minutes per mile after three miles will face elimination from the event.
Participants collect their number and chip at Race HQ before setting off at 10:00 AM sharp. Drink stations are positioned approximately every three miles along with a station at the finish line to ensure runners stay hydrated throughout the race. Portaloos are available near the start/finish area, alongside public toilets for added convenience.
First aid support is provided by professional medical teams stationed strategically across the course and at both the start and finish lines. It’s crucial that all participants complete their health information on the back of their race number to assist the medical team should any issues arise during or after the event.
Awards are presented around 12:15 PM for male and female overall winners, as well as first-place finishers in each age category. In addition to the medals and t-shirts given at the end, a selection of merchandise is available from race day onwards, including hoodies and past-event memorabilia through a jumble sale.
Parking instructions are clear: use designated public car parks within town that are signposted for easy access. Runners should avoid parking near the start/finish line to ensure smooth operations on event day.
The route map can be found online at Plotaroute, allowing runners to familiarize themselves with the course before race day. Road closures will affect parts of the route but not vehicular traffic en route to car parks or during travel back home post-race.
Post-event results and photos are made available via RunWales.com and Mick Hall Photos respectively for those wishing to relive their experience digitally.
Headphones, with the exception of bone-conducting models, are strictly prohibited in accordance with UK Athletics guidelines. Littering is not tolerated; all waste must be disposed of properly at designated stations or handed over to marshals to maintain respect for local communities and the environment.
Cut-off times encourage a steady pace but allow flexibility if runners fall behind schedule. Runners who cannot keep up may follow pavement routes, adhering to pedestrian rules until they cross the finish line.
In summary, the Caernarfon Half Marathon promises an engaging race experience that combines historical charm with athletic challenge and community spirit.
