Event accessibility
Hand-propelled wheelchair competitors are welcome at the Cardiff Half Marathon. In-depth information about the route can be found in the event’s FAQs. If you are taking part without a support runner, the event organisers recommend attaching a safety flag to wheelchairs above runners’ head height for visibility within the crowd. Please note there is no support system for mechanical problems / punctures on the course.
Support runners are able to receive complimentary entry and a high-viz bib in order to take part. To request this, and for all accessibility queries, please get in touch with the Cardiff Half Marathon directly (maria.waldron@run4wales.org).
