IRONMAN 70.3 Dhofar 2026: Expert Training and Race Guide

IRONMAN 70.3 Dhofar takes place at Hawana Salalah, Oman, on Saturday, 24 October 2026.

For professional athletes and podium or PB contenders, the challenge is sustaining an efficient swim and arriving at T1 to bike and arriving at T2 in Salalah’s warm weather conditions.

Coach de Bruin’s Assessment of IRONMAN 70.3 Dhofar

IRONMAN describes Dhofar as a bay swim, rolling bike and flat run. That profile may look fast, but it rewards control. The result is likely to depend on how well you preserve speed when bike fatigue, fuelling and heat begin to affect your run.

Before setting a target, Coach de Bruin establishes an athlete-specific bike ceiling, tests nutrition at that output and confirms whether the athlete can reproduce the required run intensity afterwards.

If power is still on target but HR or RPE climbs earlier than expected, I treat it as a “cost is rising” signal—usually heat, dehydration/fueling, poor sleep/stress, or early fatigue—so I don’t chase intensity.

I’ll first control the controllable (cooling, fluids/electrolytes, carbs, pacing discipline) and, if the drift persists for ~10–15 minutes, I cap the session by HR/RPE (or shorten it) to protect the training objective and recovery.

Swim Strategy: Spend Energy Deliberately

The swim should establish  a sustainable swim position without unnecessary physiological cost. Strong swimmers shouldn’t make the first few minutes a threshold effort for minimal gain. Athletes who are less comfortable in crowded water should work on their starts, sighting and drafting.

Coach de Bruin wants an athlete to come out of the water composed, transition through T1 quickly and go straight into the bike plan. Athletes should be ready to race with or without a wetsuit, as the final decision will be made by the race-week ruling of the organiser.

Bike Strategy: The Fastest Split That Protects the Run

Coach de Bruin would not recommend cycling power based on a general FTP percentage. The aim should also include duration, fatigue resistance, heart rate response, RPE, heat and your capacity to run thereafter.

In simulations, Coach de Bruin considers normalised power, variability, time out of position and heart-rate drift. Strong riders frequently lose more on the run than they gain by continually exceeding their ceiling. The ideal bike split is the fastest one that still allows the half marathon to be run as planned.

For a Dubai-based athlete, I assume higher heat tolerance and focus on execution: pre-cooling as needed, aggressive hydration/electrolyte targets, and pacing that keeps power steady without letting HR drift too far. 

For an athlete arriving from Europe/cooler climates, I plan a 7–14 day heat acclimation ramp (reduced intensity/volume at first, earlier sessions, more shade/indoor options), push sodium/fluids and cooling strategies harder, and I’m quicker to cap by HR/RPE rather than forcing target power until they adapt.

Ultimately treat heat like altitude.

Run Strategy: Do Not Race the First Kilometres

The first few kilometres should be enough to settle mechanics, acclimatisation and fuelling needs and the actual cost of the bike ride should become clear. RPE and heart rate might trail behind the pace when jumping straight into T2; thus, an aggressive opening split can be mistaken as a strategic move at first but will cost you later down the road.

Even if the opening section seems surprisingly easy, Coach de Bruin will still make the athlete follow the planned guardrails. Start racing when pace, heart rate, temperature response and form have stabilised, not while transition adrenaline is at its peak. The main objective is to keep your options open for later in the run. 

Preparing for Salalah’s Heat

The Khareef season in Salalah ends by October and warming air temperature is noted by IRONMAN. Heat acclimation should dictate how sustainable power, heart rate, RPE, hydration needs and fuelling tolerance are adapted.

While athletes from Dubai could get some good heat exposure, Coach de Bruin is not presumptuous in that they will be fully acclimatised and he will still be testing their response in race-specific sessions. Acclimatisation needs to be more intentional for athletes from cooler regions. Decisions should be based on sweat rate, body-mass change, fluid tolerance and recovery.

In a 70.3 race-sim ride in Dubai conditions (~34–36°C), the athlete held target IF for the first 45–60 minutes, but HR drifted ~12–15 bpm above the usual curve at the same power and RPE jumped from ~6/10 to ~8/10 despite steady watts; cadence also started to “hunt” and power became spiky on small rises. 

We adjusted by starting 20–30 minutes earlier, adding a pre-cooling routine + ice/water dousing every 10–15 minutes, increasing sodium (about +300–500 mg/hr) and fluids, and moving carbs earlier (front-loading the first hour) while slightly lowering early-bike pacing (cap HR / keep power smoother) to protect the run.

For a cooler-climate arrival, I’ve seen the same pattern show up even sooner (within 20–30 minutes) at a lower power than expected—so we use a 10–14 day heat ramp, keep the first key sessions HR/RPE-capped, and only re-test race power targets once the HR-vs-power curve normalizes.

Nutrition Must Work at Race Output

Nutrition should take into account anticipated time, body mass, glucose tolerance, sweat rate, sodium loss and conditions. Coach de Bruin does not use a single uniform intake target. He designs a plan that the athlete can tolerate and execute while still delivering the required race output.

Key rides and training bricks should test nutrition in the racing output at the race intensity. Intake, conditions, a change in body mass and subsequent run quality should all be recorded. Decide on the products, the concentration, where to put the hydration bottles and the timing of when to use them before race week.

The Training Priorities

12-8 Weeks Before the Race

Identify primary limitations: swim energy expenditure, bike power durability, aerodynamic comfort, heat response, nutrition uptake or running well after 90km of cycling. Address your bike fit, equipment and injury concerns before they affect the quality of race-specific training.

8-4 Weeks Before the Race

Long rides should include prolonged effort at race output, in race position and with race nutrition. Brick runs should verify if the bike execution enables you to mimic target run mechanics and intensity.

Last 4 Weeks Before the Race

The important simulation should include planned bike output, location, nutrition, heat and a strategic run. Coach de Bruin assesses power fluctuations, heart-rate variability, RPE, intake and how the run went thereafter, not only if the athlete finished the workout.
