Event overview
The Cardiff Winter Warmer Run is a running event on 1 February 2026 at Coopers Field, Bute Park, Cardiff (CF10 3DX). The event offers three distances:
- 5k
- 10k
- Half marathon
The Winter Warmer Runs support Shelter Cymru. Fundraising is optional and there is no minimum fundraising target. Entry prices increase on 2 January 2026 and online entries close on 24 January 2026 unless the event sells out.
Race and logistics
The course is flat and mainly on paths with one section on trail. The 5k is one lap, the 10k is two laps, and the half marathon is four laps plus an additional 1.1 km section. The route is generally wheelchair friendly and buggies are permitted, noting the trail section may be less suitable. There are marshals on course and runners are asked to keep to the left unless guided otherwise. Water is provided at the start, the finish and at the lap section. Race timing uses a chip-on-bib system with instant results displayed via Results Base; the organiser is not UK Athletics affiliated so results will appear on Results Base rather than external sites. Participants receive a medal; snacks, drinks and other small event benefits are provided. Bag storage and on-site toilets are available, and coffee and snacks are available for purchase at the event hub. Visit the organization's website for the most recent information.
