Episode Notes
Marcelo Mantecon is Florida’s all-time 5,000m high school record holder, a Nike Indoor National Champion, and an NXN finalist. And he’s only a junior in high school.
Marcelo joins the show after a soaring spring and fall season for Belen Jesuit Preparatory School in Miami, Florida, that saw him cap it off with a 4th overall finish at the Nike Cross Nationals (NXN) on December 6, 2025, with a time of 15:05.
In September, he etched his name into the Florida High School Boys XC record book, running a 14:35.25 at the Southern Showcase in Huntsville, Alabama, becoming the fastest boy to do so at the distance in the state. He then took that even lower in October by running a 14:33 in the New World Fall Spectacular.
As a sophomore last year, he was named Florida’s Gatorade 2024-25 Boys Cross Country Player of the Year. He won the 5000m National Title Indoors in March of 2025 as well.
His PRs include 4:15.83 for the mile, 8:16.86 for the 3000m indoor, 8:49.78 for the 2 mile outdoor, 14:14.38 in the 5000m indoors, and 14:33 in the 5000m for XC.
Records show you how fast he is. We’re here to dissect how he thinks; the discipline behind the breakthroughs, the pressure of carrying expectations, and what it takes to chase national greatness while still being a high school junior.
