04·Race-Day Execution

Controlled aggression, start to finish

Weather & cooling

Expect intense tropical heat peaking around 32-33°C with extreme humidity. Maximize cooling by utilizing ice and cold water baggies at every aid station to lower your core temperature, and keep a cool head.

Fuel & hydration

Extreme sweat rates require aggressive hydration of 24-32 oz (approx. 700-950 ml) of fluids per hour. Integrate high levels of sodium, using salt tablets, to counteract heavy electrolyte losses in the tropical climate.

Pacing

Do not chase power targets on the bike if headwinds are high; focus on aerodynamic efficiency and steady effort. Cap your run pace early on the shade-free course, allowing for the massive cardiovascular drift caused by the intense heat.

Gear & logistics

This is a split-transition race, with T1 at the Country Club and T2 downtown, so plan your bike and bag drop-offs carefully the day before. A rented car is highly recommended. Opt for a deep-section front wheel only if you are confident handling coastal crosswinds.

Frequently Asked Questions

What is the water temperature and wetsuit rule for the IRONMAN 70.3 Campeche swim?

The ocean swim takes place in the Gulf of Mexico where water temperatures average a warm 80°F (27°C). Because of these high temperatures, this single-loop swim is a mandatory non-wetsuit event. You will complete a straightforward, rectangular 1.2-mile course starting at Bonita Beach with a self-seeded rolling start.

How hard is the IRONMAN 70.3 Campeche bike course?

The 56-mile bike course is flat, fast, and 100% paved, featuring a minimal total elevation gain of approximately 753 feet (230 meters). However, the course is rated a moderate 6/10 for difficulty because athletes must battle strong coastal winds, high humidity, and intense heat along the out-and-back sections of Malecon Avenue. Strategic pacing and managing these elements are key to a successful ride.

What are the logistics for the split transition at IRONMAN 70.3 Campeche?

This race utilizes a split-transition setup, meaning Transition 1 (T1) is located 8 miles south at the Campeche Country Club, while Transition 2 (T2) and the finish line are situated in downtown Campeche near the Sea Gate. You will need to plan your logistics carefully the day before for bike and gear bag drop-offs. Renting a car is highly recommended to easily navigate between these two distinct locations.

What should my nutrition and hydration strategy be for IRONMAN 70.3 Campeche?

With temperatures peaking near 90°F (32°C) and high humidity, managing extreme sweat rates is critical. You should aim to consume 24 to 32 ounces of fluids per hour and integrate high levels of sodium, such as salt tablets, into your plan. Be sure to utilize the course aid stations, which offer ice, cold water baggies, sports drinks, and local Mexican-style refreshments to stay cool.

Where should I fly into and stay for IRONMAN 70.3 Campeche?

You can fly directly into Campeche International Airport (CPE) or choose Mérida International Airport (MID), which is about a two-hour drive away. For accommodations, it is highly recommended to book a hotel in the historic downtown area of Campeche near T2 and the finish line. This location simplifies your post-race logistics and keeps you close to the stunning UNESCO World Heritage site architecture.
