The training

Hyrox & CrossFit

Two engines, one goal. Mondays and Wednesdays are CrossFit and Hyrox - strength, sleds, and stations. Tuesdays and Thursdays belong to the watch: intervals and tempo to sharpen marathon pace. The rest is mileage and recovery.

The Full Hyrox

Race simulation

8 × 1 km run, each followed by a station: ski erg, sled push, sled pull, burpee broad jumps, rowing, farmers carry, sandbag lunges, wall balls.

Compromised Running

Run + station

4 rounds - 1 km run, 50 m sled push, 1 km run, 100 wall balls. Teaches the legs to keep turning over after heavy work.

Roxzone Grinder

Engine builder

1000 m row, 80 m sled pull, 100 m farmers carry, 30 sandbag lunges. Repeat for 3 rounds at a relentless, even pace.

Pain Cave

Threshold

For time - 1 km ski, 50 burpee broad jumps, 1 km row, 50 wall balls. Pure lactate tolerance under fatigue.

The routes

Runs in Puerto Rico

Where the mileage gets logged. Four routes that cover everything from flat tempo work to lung-busting hills on the island.

Paseo Lineal de Bayamón

A shaded riverside path away from traffic. Flat, predictable, and perfect for holding tempo before sunrise.

Distance: ~8 km loop
Surface: Paved trail

Milla de Oro

The financial district's straightaway. Wide, well-lit, and built for crisp repeats between the towers.

Distance: ~3 km out-and-back
Surface: City sidewalk

Old San Juan

Blue-stone streets, the city walls, and the climb to El Morro. Brutal on the calves, unmatched on the eyes.

Distance: ~5 km cobbles & hills
Surface: Cobblestone

Condado Boardwalk

Ocean on one side, lagoon on the other. The go-to easy run with a breeze and a sunrise over the Atlantic.

Distance: ~6 km coastal
Surface: Boardwalk & beach
