With RunThrough, you can expect a lively event village and clear guidance from our on-course team. After your run, enjoy food, drink and free finish-line goodies from our partners.

You can add an official event t-shirt to your entry at checkout for more than 30% off. Produced in partnership with RT Kit, it features the event logo on the chest and is the perfect keepsake to celebrate your race. Offering the t-shirt as an optional extra helps us keep entry costs lower for runners who prefer not to include merchandise.

Once you enter, you’ll receive a confirmation email straight away, and full event information will be sent to you closer to race day.

We look forward to seeing you on the start line.
