2027 Half Marathon - Cardiff

The Cardiff Half Marathon takes place on Sunday the 3rd October 2027.

We have limited charity spaces, but if you are interested in running and fundraising on behalf of Joseph’s Smile, please fill in the enquiry form on this page. We are delighted to offer FREE entry but with a pledge to raise a minimum of £300.

Our charity must pay a £125 registration fee per runner and an additional £20 for a running t-shirt. To help cover these costs and raise vital funds for our cause, we ask each runner to commit to raising a minimum of £300. Unfortunately, we can only accept runners who are able to make this commitment

Once your place has been confirmed, we’ll provide you with a Joseph’s Smile running vest or sports T-shirt to wear on race day.

We kindly ask that you aim to raise a minimum of £145 by 1 August 2027, or agree a fundraising plan with us so we can support you in reaching your target by race day.

If you are finding fundraising challenging, please do get in touch. We’re here to help. However, as places are limited, participants who have not reached the minimum fundraising target or agreed a fundraising plan by this date may risk losing their place.
