Dubai's endurance calendar has a new anchor point. The T100 Triathlon, now in its third edition, moves to Al Mamzar this year, running from 13 to 15 November 2026 as the penultimate stop on the nine-race T100 Race to Qatar tour.
The venue switch matters for spectators and competitors alike. Al Mamzar sits on Dubai's northeastern coast, where the emirate borders Sharjah, and the new course makes the most of it. Swimmers start in the calm water off Al Mamzar Beach, cyclists then push through Al Hamriya Port and across the Dubai Islands, and the run winds along the shaded paths of Al Mamzar Park before finishing on the corniche footpath. It's a more scenic, parkland-flavoured route than a pure city circuit.
There are three ways to race. The Sprint is the entry point: a 750-metre swim, 20-kilometre ride and 5-kilometre run. The Olympic distance, new for this edition, doubles up to 1.5 kilometres in the water, 40 on the bike and a 10-kilometre run. The signature T100 is the serious one — 2 kilometres swimming, 80 kilometres cycling and 18 kilometres running, adding up to a full 100 kilometres of effort.
Entry fees vary by category and start from Dhs674, with registration open through the event's official website. You don't need to be racing to join in, though. Last year's edition pulled in nearly 8,000 amateur participants and more than 15,000 spectators over the weekend, and the 2026 field is tracking at around 2,000 athletes from 57 nationalities. More than a third of those are returning from the inaugural season, which says something about how the event has landed.
The triathlon slots neatly into Dubai's cooler-month fitness run, arriving alongside the city-wide Dubai Fitness Challenge and a growing list of free outdoor workouts. November is when the emirate emerges from summer and everything moves back outside — which is exactly why the race weekend works so well for visitors.
For travellers, this is a good excuse to build a trip around sport. Fly in for the weekend, watch or race in the morning, and you've still got beaches, the Dubai Islands and the rest of the city to explore. Spectating is free, and the Al Mamzar setting — park, beach and corniche in one spot — is easy to enjoy even if you've never considered a triathlon in your life.
