From zero to the finish line
20 weeks
This 20-week plan is specifically engineered to handle the massive 1615m bike climb and severe tropical heat. We front-load climbing strength and upper-body swim endurance, culminating in intense heat-acclimation protocols and race-pace simulations so you can tackle the hilly highway and hot run with absolute confidence.

Aerobic & Thermal Prep
Build basic aerobic volume while initiating mild heat exposure.
WK 7–12
Strength & Climb Specialization
Focus on low-cadence climbing power and non-wetsuit swimming volume.
WK 13–17
Race-Specific Simulation
Incorporate long, hot brick workouts and high-intensity highway pace simulations.

Taper & Heat Peak
Reduce volume to shed fatigue while maintaining heat acclimation protocols.
Adapts to your fitness, schedule & recovery every week.
With air temperatures soaring to 34°C, aggressive cooling is mandatory. Grab ice and water at every single run aid station to douse your head and body, keeping your core temperature down.
Fuel & hydration
The non-wetsuit swim and tropical heat mean high sweat rates; target at least 800-1000ml of fluid per hour on the bike. Supplement with high-sodium mixes or salt tablets to offset heavy electrolyte loss and prevent cramping on the steep climbs.
Pacing
Manage your effort strictly on the initial 200m climb out of T1; spiking your heart rate early will ruin your day. Maintain a conservative power target on the long highway climbs to save your legs for the rolling, hot 180m run.
Gear & logistics
Opt for a highly ventilated aero helmet and a white, sun-reflective tri suit to combat the intense tropical sun. Mid-depth wheels are ideal for managing the heavy highway winds without sacrificing speed.
Frequently Asked Questions
What is the water temperature and wetsuit policy for the IRONMAN 70.3 San Salvador swim?
The swim takes place in Lake Ilopango, where the water temperature is exceptionally warm at 27.5°C (81.5°F). Because of these warm volcanic crater lake conditions, the 1.9 km swim is strictly non-wetsuit legal. You should prepare to race in a swim skin and practice your pacing to manage the warm freshwater environment.
How hard is the IRONMAN 70.3 San Salvador bike course?
The bike course is rated as highly challenging, featuring a massive 5,301 feet (1,615 meters) of total elevation gain over its 90 km distance. This two-loop route along the Pan-American Highway begins with a sharp 200-meter climb straight out of transition, followed by long, gradual climbs and technical descents. You must also prepare for heavy wind exposure along open segments of the highway.
What is the run course like for IRONMAN 70.3 San Salvador?
The 21.1 km run is an urban, rolling course through the historic core of San Salvador with 591 feet (180 meters) of elevation gain. Because there is minimal shade, you will face direct sunlight and rising tropical temperatures as you head toward the finish line at Plaza Gerardo Barrios. Proper heat management and pacing on the undulating city streets are essential for success.
What should my nutrition and hydration strategy be for IRONMAN 70.3 San Salvador?
With ambient temperatures rising from the low 70s°F at sunrise to the low 90s°F by midday, sweat rates will be exceptionally high. You should prioritize high-sodium hydration and electrolyte replenishment from the very start of the race. Carrying extra salt tablets or custom-mix powders is highly recommended, alongside using every aid station to douse yourself with water.
Which airport should I fly into for IRONMAN 70.3 San Salvador?
You should fly into El Salvador International Airport (SAL), which is located approximately 45 minutes away from the capital city of San Salvador. It is highly recommended to pre-arrange private transport or official race shuttles to handle your bike bag smoothly. For lodging, booking accommodations near the historic city center or Zona Rosa will provide the easiest access to the race venues.
