04·Race-Day Execution

Controlled aggression, start to finish

Weather & cooling

Expect mild temperatures around 20-22°C, but high humidity and direct sun on the run can increase core temp quickly. Grab water at every aid station to pour over your head, and apply high-SPF sunscreen before the race and in T2.

Fuel & hydration

Aim for 80-90g of carbohydrates per hour on the bike, utilizing the flatter sections to eat since climb-induced high heart rates make digestion harder. Aim for 750ml of fluid per hour, especially during the long, warm climbs.

Pacing

Keep your effort strictly capped below threshold on the initial Puerto de Ojén climb; blowing up here will ruin your race. Use the descent to recover, and transition into a metronomic, steady tempo on the flat, two-loop run.

Gear & logistics

Choose a cassette with a climbing gear to keep your cadence above 70 RPM on steep sections. Opt for mid-depth wheels to balance aerodynamic efficiency on flats with stability during fast mountain descents.

Frequently Asked Questions

What is the water temperature and swim format for IRONMAN 70.3 Marbella?

The swim takes place in the Mediterranean Sea at Levante Beach with expected water temperatures ranging between 18°C and 21°C (64°F to 70°F), making it typically wetsuit-legal for age-groupers. You will complete a single-loop, counter-clockwise 1.9 km (1.2-mile) course starting with a rolling beach start. Because you swim directly out into the open sea, be prepared for potential swells and practice sighting buoy markers against the morning sun.

How hard is the IRONMAN 70.3 Marbella bike course?

The 90 km bike course is highly challenging and technical, featuring approximately 1,400 meters (4,593 feet) of elevation gain as you head inland into the Sierra Blanca mountains. You will tackle the major ascent of Puerto de Ojén early in the ride, followed by fast, winding descents that require excellent bike handling skills and cautious braking. A gearing setup such as a 34T or 36T inner chainring paired with an 11-30T or 11-32T cassette is highly recommended to manage the steep gradients.

What is the running route like for IRONMAN 70.3 Marbella?

The run is a flat, fast 21.1 km (13.1-mile) course consisting of two laps along the paved Paseo Marítimo promenade. It offers flat terrain and roaring spectator support, but the coastal path is entirely exposed to the elements. You should prepare for direct sun exposure and potential coastal headwinds by practicing your pacing and staying disciplined with hydration at the aid stations.

What weather should I expect in Marbella in late October?

Marbella in late October offers highly pleasant racing conditions, with average daytime high temperatures around 22°C (72°F) and morning lows near 15°C (59°F). While the air is generally comfortable, the autumn transition can occasionally bring strong coastal winds or sudden Mediterranean showers. Pack versatile gear, including a light wind jacket for pre-race morning prep and transition setup.

Where are transition and the finish line located for IRONMAN 70.3 Marbella?

The race features a single, centralized transition area (T1/T2) located directly at the Puerto Banús marina, which simplifies your race-day logistics. The final run finish line is also situated in the heart of Puerto Banús, right along the vibrant waterfront. This compact layout means your support crew can easily cheer you on during the swim exit, transition phases, and the final red carpet run.
