Race Intelligence · Da Nang, Vietnam
Da Nang gives full-distance athletes a warm sea start at East Sea Park, fast coastal roads and two crossings of Cua Dai Bridge before a marathon along the beachfront. The flat profile looks generous. In the tropical heat, it can become unforgiving.

Your day in Da Nang
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Da Nang could look like.
The course behind your race
From East Sea Park, the 3.8 km swim leads into 180 km beside the coast and Han River, towards Quang Nam and over Cua Dai Bridge. Then come four beachfront marathon circuits. The roads can give you speed, but the heat can take far more than an over-ambitious bike split earns.
East Sea Park, opening sea lap
A rolling start into a two-lap triangle course is straightforward to navigate. At near 29C, the water is already warm enough to be part of the day's heat load, so settle rather than race the first lap.
Settle by 400 m. Pace by effort, not by the easy rolling-start entry.
East Sea Park, second sea lap
Along the Vo Nguyen Giap coastline and the Han River's eastern bank, the flat, fast terrain invites a power number the extreme heat won't let you hold. Set the ceiling now.
Cap power before the heat peaks. Start fluid and electrolyte intake early.
Võ Nguyên Giáp coastal road
The 16.5 km Lac Long Quan straightaway leads to a genuine ascent over the Cua Dai Bridge. Ride it under control rather than pushing to hold speed on the climb.
Hold your power number on the bridge climb. Stay on the fuelling schedule.
Lạc Long Quân and Cua Dai Bridge
The uninterrupted straightaways here are built for speed, and built for overspending in the day's rising heat. Ride to your plan, not to what the fast road allows.
Recheck power against the heat, not the terrain. Drink on a schedule, not on thirst.
Repeated riding towards Quang Nam
Repeating the loop and crossing the Cua Dai Bridge once more, the heat is now at its worst. Protect the run by holding your number rather than chasing time back.
Finish nutrition before T2. Prioritise core temperature over splits.
Cua Dai return towards Da Nang
The run's flat, out-and-back beachfront loops offer no shade and no terrain to slow you down, in conditions already among the hottest this project has modelled. Start well under the pace the flat road invites.
Use aid stations every 1.3-1.4 km fully. Hold effort, not pace, from the first kilometre.
First beachfront marathon circuit
Reaching the familiar 5.9 km turnaround a second time, reassess pace against how the heat actually feels, not against the flat course's reputation for speed.
Reassess goal pace against the heat. Cool at every aid station.
Middle beachfront marathon circuits
This is where extreme heat and a fast-but-flat course combine to punish an early pacing mistake most. Ease pace before form breaks down.
Use ice or cold sponges at every station. Keep drinking on schedule regardless of pace.
East Sea Park, closing marathon circuit
The finish back at East Sea Park, among Da Nang's electric beachfront crowds, rewards a day paced to the heat rather than against it.
Decide the finish honestly. Keep hydrating even in the closing kilometres.
Walk through the 2027 full-distance course from East Sea Park: two sea laps, the Cua Dai Bridge crossings, bike turnarounds and four beachfront marathon circuits. Check current aid, heat, water rules and road closures. The companion 70.3 shares the city, not your full-distance split plan.

Prepare for Da Nang
A finish range gives you something to work towards. The preparation is specific to this race: a full 3.8 km sea swim, 180 km bike nutrition plan and patient marathon opening are rehearsed independently of the familiar half-distance programme.
I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Da Nang.
