KidneyWales Cardiff 10K closures on 6 September
Thousands of runners are expected in Cardiff for the KidneyWales Cardiff 10K on 6 September 2026. The 10K starts at 10am on a Cardiff city-centre route, with rolling road closures scheduled from 9am until 1pm.
The event is intended for runners. Cardiff Council’s notice does not state a price or booking process, and it provides no specific venue address, transport guidance or accessibility information.

The confirmed race-day schedule
The race itself begins at 10am, but its effect on city-centre roads starts an hour earlier. Cardiff Council says a rolling road closure will operate along the route from 9am until 1pm to facilitate the event.
For participants, 10am is the only confirmed programme time in the supplied information. No assembly time, arrival window or other race-day schedule has been published in the council update, so runners will need to rely on their separate entry information for any instructions beyond the confirmed start time.
For residents and other road users, the relevant period is the full four-hour closure window rather than the race start alone. Journeys that cross the city-centre course could be affected before runners set off and after the 10K has begun.
What the rolling closures mean for planning
The council describes the restrictions as rolling closures along the route. However, its update does not name the affected streets or give a section-by-section timetable. It is therefore not possible from the supplied notice to establish which individual roads will close first, how long each section will remain restricted or exactly when access will resume at a particular location.
Anyone planning a city-centre journey on 6 September should treat 9am to 1pm as the confirmed period of possible disruption. The information supports planning around that overall window, but not estimating a narrower closure time for a specific street.
What has—and has not—been announced
The confirmed event programme is concise: a KidneyWales 10K race on a Cardiff city-centre route, starting at 10am, with thousands of runners expected and rolling traffic restrictions operating from 9am to 1pm.
Cardiff Council published the details in its 28 August 2026 Friday update as a plan-ahead notice. The update does not supply an exact venue address, route map, list of closed roads, entry price, booking link, transport arrangements or accessibility details. Those omissions should not be read as confirmation that the event is free or that no additional participant arrangements apply.
The firm planning point from the Cardiff Council Newsroom source is that city-centre road restrictions may operate anywhere along the race route between 9am and 1pm on 6 September.
