Race Day in Barranquilla: Timeline, Classic Mistakes, and a Plan B for When the Heat Makes the Call

The Days Before

Day -5 to -3: arrive in town and start active heat acclimation. Short sessions during the hot hours, never exhausting. Recon the two hubs of the race: Playa Puerto Mocho (swim and T1) and Gran Malecón del Río (run and finish). If you can, swim at the race venue to get a feel for the water and conditions: the official description talks about calm, warm water where the Magdalena meets the sea.

Day -2: bib pickup and expo. Read the race briefing and check the cutoffs, which weren't published on the pages we reviewed and will be in the athlete guide. Check the official communication on water temperature: wetsuits are legal only at 24.5°C or below, and in a Caribbean sea the likely scenario is a non-wetsuit swim.

Day -1 (Saturday): in 2026, bike check-in ran from 11:00 to 17:00 at T1 on the beach. Go early, photograph your bike's position and landmarks so you can find it in the dark. Memorize the flow: swim exit, path to your bike, bike out. Then: a tried-and-tested meal, bottles in the fridge, double alarm, early to bed.

Race Morning

Wake up with plenty of margin: you need to get to Puerto Mocho, pump your tires, set up your nutrition, and do it all before transition closes. At a race in its second edition, transfer logistics aren't as dialed as at a long-established 70.3: add a 30-minute buffer to any estimate.

Breakfast tested in training, 2.5-3 hours before the start. From the get-go, small sips of water with sodium: in Barranquilla you start in a deficit if you don't pre-hydrate. At dawn the low is around 25°C: it won't feel hot. It will be.

The Classic Mistakes (and How to Avoid Them)

1. Pacing like it's a temperate climate. The number one mistake. Your target time needs recalibrating for 34°C: race reports from the first edition describe a brutal day precisely because of heat and humidity. Start with your "hot weather" goal, not your winter training goal. 2. Drinking only when you're thirsty. On the bike, set a timer every 10-15 minutes. At these temperatures, thirst shows up late. 3. Pushing on the out-and-back. Seeing your rivals face to face on the Circunvalar tempts you to race too early. The race starts at km 10 of the run. 4. Skipping aid stations on the run. Every aid station is a cooling station: ice, water over your head, sips. The seconds you lose are the minutes you gain later. 5. Trying anything new. No nutrition, gear, or clothing you haven't tested. That counts double in the heat.

Plan B: When the Day Doesn't Go to Plan

If the morning announcement puts the water above 24.5°C (likely): no wetsuit. If you've trained swimming in a tri suit or swimskin, nothing changes. If you haven't, swim more conservatively and accept an extra 2-3 minutes.

If on the bike you realize you're above your target pace: cut 10-15 watts right away, up your fluids and sodium, and consider your time goal shelved. Saving the run is worth more than 5 minutes on the bike.

If heat stroke warning signs show up on the run (chills in the heat, skin that stops sweating, confusion): stop at the aid station, cool down, assess with race staff. No finish line is worth a hospital stay.

If you flat or have a mechanical: on a single 90 km loop there's no second pass. Carry a full kit for two flats and know how to use it.

The Finish Line

The finish is on the Gran Malecón, with a first-edition crowd that official videos show as big and loud. More than 1,200 athletes from 27 countries finished the first edition: a young race, but with a finish line that's already memorable. Enjoy it: you'll have earned it at 34 degrees.
