About the race
The Cardiff Half Marathon is scheduled for 3 October 2027. Entry for the event is managed primarily via a Ballot: the Ballot opened on 1 October and closed on 18 October 2026, with results announced on 22 October 2026. Separate UK and International Ballots operate to allocate spaces, and it is free to enter the Ballot; the UK Ballot entry fee is £59 and the International Ballot entry fee is £70, plus the registration platform booking fee.
A reserved allocation of 1,500 discounted spaces is available for Welsh Athletics members at a £54 entry fee. Several “Skip the Ballot” options and charity or tour operator entries exist, including an NSPCC Fundraiser option priced at £40 when pledging to raise £300. Registration for charity and other alternative entry routes opens on Ballot Results Day. The event covers a 13.1 mile course on fully closed and marshalled city centre roads and enforces a 4 hour cut off. Entries include a race pack with race number and timing chip, access to the event village and feed stations, course entertainment and live music, live tracking via the Run 4 Wales app and finish time SMS, pacers in each start wave, and a finisher medal plus a technical finishers tee or a Climate Action Fund donation option. Terms specify participants must be 17 or older, fit to run, and not under the influence of drugs or alcohol.
Ballot entries are subject to the event terms and are generally non-refundable, with limited exceptions. Transfer or gifting of a place is possible up to the published booking edits deadline. Junior family races take place on Saturday 2 October and SuperHalfs participation and voucher redemption are supported. Visit the organization's website for the most recent information.
