Adapts to your fitness, schedule & recovery every week.
Expect cool morning air warming up to 28°C by the afternoon. Use the early aid stations on the run to pour water and use sponges over your neck to keep core temperatures down.
Fuel & hydration
Utilize the official on-course Precision Hydration and Maurten gels. Target 60-90 grams of carbohydrates and 600-800ml of fluids per hour, adjusting upwards if afternoon humidity and heat rise.
Pacing
Hold back on the fast, flat stretches of the bike to save your legs for the technical run. Smoothly ride the sub-3% grades and keep your effort controlled on the final steep 10% ramp.
Gear & logistics
Prepare your split-transition bags (Blue for T1, Red for T2) on Saturday. Use a deep-section front wheel or disc rear wheel for the fast bike course, but be ready for moderate crosswinds on the plains.
Frequently Asked Questions
What is the water temperature and wetsuit policy for the IRONMAN 70.3 Vitoria-Gasteiz swim?
The water temperature in Ulibarri-Gamboa Lake typically ranges from 20°C to 22°C (68°F to 71°F) on race day. This means the 1.9 km single-loop swim is usually wetsuit-legal under IRONMAN rules. You can expect very clean, calm, drinking-quality freshwater with negligible currents as you swim in Landa Provincial Park.
How hard is the bike course at IRONMAN 70.3 Vitoria-Gasteiz?
The bike course is relatively fast and beginner-friendly, featuring a single 90 km loop with 500 meters of total elevation gain on highly smooth tarmac. Most of the rolling terrain maintains a gentle gradient of under 3%, though you should prepare for a challenging short ramp reaching up to a 10% gradient near the end of the course. Wind exposure on the open Alava plain can be moderately high, so staying aerodynamic on a tri-bike or with clip-on aerobars is highly recommended.
What is the run course profile like for IRONMAN 70.3 Vitoria-Gasteiz?
The run is an exceptionally flat 21.1 km, two-loop urban course with approximately 240 meters of total elevation gain. It winds through the historic old town, which features tight twists, multiple 180-degree turnarounds, and cobblestone streets that can disrupt your running rhythm. Because there is minimal natural shade, managing your pacing and cooling down in the afternoon heat of up to 25°C to 28°C (77°F to 82°F) will be your primary challenge.
How do the split transitions work at IRONMAN 70.3 Vitoria-Gasteiz?
This event utilizes a split transition format where T1 is located at Lake Landa and T2 is in downtown Vitoria-Gasteiz. You will need to organize and pack your color-coded transition bags (Blue for T1, Red for T2) on Saturday before the race when you rack your bike. On race morning, you can take the official shuttle buses from the city center up to the swim start and T1.
What nutrition is provided on the course for IRONMAN 70.3 Vitoria-Gasteiz?
The official on-course aid stations will provide water, Maurten energy gels, and Precision Hydration sports drink served in 750ml bottles. It is highly recommended to establish a consistent hydration schedule on your bike using aerobar-mounted and rear bottles. For the run, make sure to utilize the available water and cooling sponges at every aid station to manage the warm afternoon temperatures.
