Caernarfon Half Marathon

The event is a Half Marathon held in Caernarfon that starts and finishes next to Caernarfon castle. The course includes a few small uphill sections and some longer downhill sections. There will be some road closures, but not all roads are closed to traffic; runners should keep to the left unless instructed otherwise.

Race headquarters and number/chip collection are located next to the start/finish. Drink stations are provided at approximately every three miles and at the finish; runners who require extra water are advised to bring a bottle. Toilets are provided as portaloos near the start and finish, with additional public toilets nearby. A baggage area accepts small bags but organisers advise against leaving valuables.

First aid cover is provided by a professional medical team, with stations at the start, finish and on course; runners should complete the medical history information on the back of their race number. If a runner withdraws they must notify a marshal and return their timing chip to race headquarters. Road closures will reopen on a rolling basis.

There is a strict time rule: each mile must be completed in under 15 minutes or the runner may be removed after the third mile. Organisers also ask participants to be able to maintain roughly a 12 to 15 minute per mile pace and complete the half marathon in about 3 to 3.5 hours; slower runners may be directed to use pavements and follow the highway code. Headphones are not permitted except bone conduction types. All finishers receive a technical T-shirt and a bespoke medal; prizes are awarded for overall and age-category places. Free entry options exist for a hospice place with minimum sponsorship. Visit the organization's website for the most recent information.
