The run: three laps through downtown San Salvador, in serious heat

The course

Three urban laps through the historic center of San Salvador: 21.1 km with roughly 180 m of total elevation gain (591 feet, official figure). This is not a flat half marathon. A race report from the 2026 edition mentions about 200 m of climbing on the run and calls the race very tough overall. The three-lap format means you'll face the same short climbs three times, each time more tired and in higher temperatures.

The upside of the urban circuit: the crowds. Reports describe constant, energetic support along the entire course, with the whole historic center involved in the event. The inaugural 2026 edition drew 1,200 athletes from 28 countries and the city showed up. When you hit lap three on heavy legs, that support will matter.

The real opponent: the heat

In February, typical highs sit around 30°C. You'll come off the bike in late morning, during the hottest hours. The course offers little shade. Several 2026 race reports describe the run as the hardest part of the race precisely because of heat management.

The good news: in 2026 the aid stations were described as well stocked and consistent, with ice, water and sponges available throughout the race. That gives you a real tool. Use it systematically:

• Ice in your tri suit at every pass, front and back.
• Sponges on your neck and head, then tuck them under your top on your shoulders.
• Water on your body, not just in your mouth.
• Drink at every aid station, even if you don't feel thirsty: in this heat, thirst shows up late.

Pacing: the bill comes due on lap three

The three-lap structure is a test of discipline. The first lap will feel easy: fresh legs off the bike, crowds, adrenaline. It's a trap. The plan:

1. Lap 1: start 10-15 seconds per km slower than your goal pace. Assess how you're handling the heat. Get familiar with the short climbs. 2. Lap 2: settle into your rhythm. If you're feeling good, move to goal pace. Keep cooling at every aid station without skipping a single one. 3. Lap 3: this is where it's decided. If you've managed well, you can finish strong; if you overdid it on the first two laps, the heat presents the bill right here.

The ballpark times on the race card (our estimates, not official): 2:40 for a comfortable finish, 2:15 for a mid-pack goal, 1:55 for the fast crowd. Compared to a flat half in cool conditions, budget an extra 10-20 minutes.

How to prepare

• Heat acclimation: if you're training through a European winter, the final weeks before the race are critical. Runs with extra layers, post-workout sauna if you already use one, or arriving in San Salvador a few days early. Without acclimation, February's 30°C will cost you dearly.
• Rolling terrain work: build sections with grade and pace changes into your long runs. 180 m of elevation gain isn't a mountain, but over three laps it breaks the rhythm of anyone used to flat courses only.
• Cooling rehearsal: in at least one long workout, simulate dumping water and ice on yourself. You'll find out whether wet shoes give you blisters and how your tri suit responds.

The decision to make

Set a maximum pace for the first lap before the race and stick to it, no matter what your legs say. And decide on a plan B: if your heart rate climbs above threshold at easy pace on lap two, switch to walking the aid stations and the climbs. In San Salvador, finishing well is worth more than ten minutes saved on paper.
