If you're in Cape Town on Sunday, 18 October 2026, the car might not be your friend. The annual Nelson Mandela Marathon sends thousands of runners through the city centre and Atlantic Seaboard, and to keep them safe, authorities are rolling out staged road closures from midnight onwards — with some streets shut well before race day itself.
Four races start between 05:30 and 08:30, all finishing at the Grand Parade. Roads reopen progressively through the morning as each section clears, but exact timings depend on how the field moves and official safety sign-offs. Information boards along the routes will show the specific closure times for each road.
A couple of closures kick off early. Darling Street, between Corporation and Buitenkant streets, closes from midday on Saturday 17 October and only reopens at 05:00 on Monday 19. Strand Street, from Adderley to Castle, shuts at midnight on Sunday and reopens at 10:30 that morning.
On race day, the picture gets wider. In the Bo-Kaap, Chiappini Street and Yusuf Drive are closed until around 11:30. City Bowl routes Buiten and Dorp streets run the same pattern. District Six sees Chapel, Constitution and Russell streets shut from 04:30 to 10:30. Over towards the coast, Somerset Road in Green Point is closed the longest — 04:30 to 13:30 — with Fritz Sonnenberg Road close behind. Sea Point's Beach Road and Main Road are affected between roughly 05:00 and 12:00, and in the Foreshore area Adderley Street and FW de Klerk Boulevard are restricted from 05:30 to 13:30. In the city centre, Darling Street closes at 06:00 and only partially reopens by 14:00.
It's not a total lockdown: local access will be maintained in some zones, with marshals managing entry for residents. Officials suggest anyone driving into the city wait until after lunch, and specifically advise avoiding the city centre, Atlantic Seaboard and Paarden Eiland on Sunday morning.
For travellers, the takeaway is simple: if you're staying in or near the CBD, the Bo-Kaap, Sea Point or Green Point that weekend, either plan around the closures or lean into them. The marathon finish at the Grand Parade, the historic square next to City Hall, makes for a lively morning of spectating — and Sunday afternoon is a fine time to explore streets that were choked with traffic a few hours earlier. If you have an airport transfer, a car hire pickup or a wine-lands day trip booked for that Sunday morning, build in generous extra time or shift it to the afternoon.
