Dubai T100 Triathlon 2026 Moves to Al Mamzar: The New Coastal Course

The new Dubai T100 triathlon route

The move is the headline. After building its reputation at Meydan, the Dubai T100 triathlon route now runs along the coast at Al Mamzar, using the beach for the swim and the surrounding parkland and roads for the rest. It is a different face of the city, and organisers have leaned into it.

The bike course heads out through Al Hamriya Port and Dubai Islands before climbing onto the Infinity Bridge, passing Port Rashid and the Queen Elizabeth 2, with the Dubai Frame and Burj Khalifa rising beyond, then turns for home back to Al Mamzar. The run takes in the shaded paths of Al Mamzar Park and the newly opened corniche footpath — welcome shade for a November race. Dubai sits as the penultimate stop on the nine-race T100 Race to Qatar, with the World Championship Final in Qatar on 10-12 December, and the whole weekend lands inside the 10th Dubai Fitness Challenge, which runs from 31 October to 29 November.

What the elite race actually is

The "100" is the clue: the professional T100 is a 2km swim, an 80km bike and an 18km run, 100km in total, according to the series organisers. The world's best race four of these weekends before the Qatar final decides the season. At the 2025 edition, Switzerland's Julie Derron won the women's race and the USA's Morgan Pearson took the men's — the kind of names that make a home crowd worth turning up for.

Dubai T100 triathlon distances: which one can you enter?

Here is the part the headlines skip: you do not have to be a professional to line up. Around 8,000 amateurs raced the 2025 edition, and for the first time the 2026 amateur programme adds relay options for the T100 and Sprint distances, plus a brand-new Olympic distance. That means there is a start line for almost every level.

New to the sport? A relay lets you split one of those distances across a team of friends, so you own just the swim, the bike or the run while someone else covers the rest. If you would rather go solo, the Olympic distance is the sensible first target before you ever think about the full T100. Not sure where you sit? A few sessions with a coach will tell you fast — our personal trainers map out exactly that kind of build.

Training for an open-water sea swim

The swim is the leg that unnerves most first-timers, and a sea start off Al Mamzar beach is a different animal to lane swimming. The good news: it is very trainable, and the warm Gulf water is friendlier than most open-water venues in the world.

Practise sighting

In a pool you follow a black line; in the sea you have to lift your eyes every few strokes to spot a buoy and keep swimming straight. Drop that "sighting" habit into your pool sets now — glance forward, then roll back into your stroke — so it is automatic on race day. Our exercise library is a good place to drill the mechanics.

Get used to saltwater and a beach start

Saltwater floats you higher, which changes your body position, and a beach start means a short run into the water before you settle into a rhythm. If you can, train in the sea a few times before November so none of it is a surprise. Warm water also means many athletes skip the wetsuit — so practise the way you plan to race.

Build a bigger engine on the bike and run

A triathlon is won and lost on staying strong across three back-to-back efforts, so the real fix is aerobic fitness. Steady indoor cycling like an RPM class builds the legs for that 40km or 80km ride without the traffic, and short, sharp conditioning sessions teach your body to hold pace when it is tired. Two or three focused sessions a week, layered from now to race week, is plenty.

Thinking about your first triathlon?

You do not need to sign up for the full 100km to get race-ready — you need consistent swimming, cycling and running, and a place to do all three when it is too hot to train outside. Come and try GymNation with a free day pass, use the pool and the floor, and see how quickly a start line at Al Mamzar starts to feel realistic.
