04·Race-Day Execution

Controlled aggression, start to finish

Weather & cooling

Expect cool morning air around 11°C warming to 23°C by midday. Use the run aid stations every 1.5 to 2 km to douse your head and body with water and sponges to combat the direct midday sun.

Fuel & hydration

Target 60-90g of carbohydrates per hour on the high-speed bike using the four aid stations. On the flat, fast run, drink at every station to maintain hydration in the dry, warm afternoon air.

Pacing

Keep your effort controlled on the steady Sierra de la Calderona climbs to save your legs. Maintain a stable aero position on the fast descents and flat coastal roads to maximize speed against the headwind.

Gear & logistics

With a split transition, rack your bike and blue bike bag at T1 on Saturday, and drop your red run bag at T2. Use a moderate wheel depth to stay stable in the unpredictable coastal crosswinds.
