Mexico also scored a 1-2-3-4 sweep in the Female 16-19 at the sprint distance and 1-2-3 sweeps in Male 20-24 sprint distance, Male 30-34 standard distance, Male 30-34 sprint distance and Male 45-49 standard distance.

The U.S. posted a 1-2-3-4 sweep in Female 60-64 at the standard distance.

National medals hauls

In an international World Championship, it is natural for nations to vie for bragging rights. The ITU Triathlon Grand Final in Cozumel was no exception as athletes for host country Mexico had a spectacular performance, squaring off with North American rival United States for the most gold and most total medals.

It is a given that host countries almost always reap strong medal performances. In the Olympics, it is a result of national pride – the host country invests more in Olympic athletic development. See Russia (albeit with chemical chicanery) at the 2014 Sochi Winter Olympics, the U.S. at the 1984 Olympics in Los Angeles, the Chinese at Beijing in the 2008 Olympics, and so on. In ITU triathlon world championships, where amateurs compete on their own dime for medals, travel costs are the biggest factor. Europeans dominate in Europe, U.S. triathletes shine at home.

In Cozumel, the Mexican triathletes proved something more than just a home court advantage. While the U.S. team had to travel a bit more, U.S. to Mexico flights were much less than trips from Europe, Asia, South America and Oceania. While Mexico has acquired international respect for the achievements of elites like Crisanto Grajales and Claudia Rivas, USA Triathlon has a long history of grass roots development, professional success, a bigger economy, and a bigger population to draw from. And so, Mexican triathletes’ performances at Cozumel, taken in context, were an outstanding achievement.

So how close were the two nations?

In terms of triathlon gold medals, United States athletes eked out a slim victory – 17 gold to 16 gold for Mexico.

In the total triathlon medal race, Mexico scored 51 in triathlon – 16 gold, 20 silver and 15 bronze. The U.S. had 48 triathlon medals – 17 gold, 12 silver and 19 bronze.

In Aquathlon, the U.S. dominated in gold medals with 10 to Mexico’s 3. However, in total Aquathlon medals, Mexico and the United States tied with 18 apiece.
