Dubai T100 triathlon weekend: swim at Al Mamzar, finish at Meydan, 13 to 15 November

The Dubai T100 triathlon comes back for a full weekend from Friday 13 to Sunday 15 November, with races for amateurs on the Saturday and Sunday mornings and an event village at Meydan Racecourse. It falls in the middle of the Dubai Fitness Challenge, which runs until 29 November, and is one of the season's few chances to watch a triathlon in the city.

The race is split across two places. Every swim starts at Al Mamzar Beach Park, where the first transition, from swim to bike, also sits. The bike leg ends at Meydan Racecourse, which hosts the second transition, the finish line, the expo and race pack collection. The course runs on closed roads; the organiser has not yet published road closure times and says start times could still move once they are final.

Saturday 14 November opens with the Olympic distance triathlon at 6.45am. Sunday 15 November has the 100km race, the event's longest, at 6.45am, followed by a sprint triathlon at 10.45am, the shortest and the one most first-timers choose. Friday is for athletes: race packs and bike check-in for the Olympic race at Meydan from 4pm to 7.30pm.

Watching is free. Spectators are advised to park at Meydan and take the free shuttle bus to the beach for the swim start; return buses leave once the last swimmer is out of the water. Back at Meydan the village has live music and DJs, food trucks, photo spots and a children's zone, so families can wait for the finishers there.

If you want to race rather than watch, registration is still on the organiser's page, which lists the Olympic, sprint and 100km races; fees are shown when you sign up. Read the refund rules before you pay: 50 per cent back until 90 days before race day, 25 per cent up to 30 days before, and nothing after that, so a late entry cannot be refunded. Athletes need to be at the swim start at least 20 minutes before their wave, and the athlete guide on the T100 site has the full timetable and course maps.
