boruca | IAN CORLESS

The Coastal Challenge Costa Rica pulled runners away from the coastline and into the high farmlands of the country’s interior. It was a bruising day, 37.7 kilometers with 2,613 meters of climbing for the Expedition category.

No hiding from it. The terrain rolled relentlessly, climbing and plunging through rough rural tracks and exposed hillsides before dropping toward the finish in Palma Norte. It was a stage built to test already tired legs, and it did exactly that.

Men’s Race

Erick Aguirre ran smart. With a solid overall lead, there was no need to take risks. He spent the day alongside Jesus Cerdas, the pair moving steadily across the harsh terrain. They crossed together in 6:05:43, controlled and composed.

Behind them, the real battle unfolded.

Jon Shield fought all day. For much of the stage he sat in fourth, but he never let the gap grow. Gradually he reeled in Martin Alonso Mena. The two arrived at the line almost inseparable after more than six and a half hours of racing. Shield edged it by just three seconds, 6:38:26 to 6:38:29. A long day decided by the smallest of margins.

Women’s Race

Denise Zelaya continues to run her own race. Calm, consistent, and completely dominant, she finished in 7:29, well clear of the field.

Janina Beck followed in 8:27, with Floribeth Perez completing the podium in 8:59. On a day that punished everyone, Zelaya once again showed control and strength.

Adventure Category

The Adventure course was shorter at 12 kilometers, but still far from easy. Sammy Francis ran solo again, crossing in 3:39:22 with another composed performance. In the women’s race, Laura Zuniga finished in 4:13:45, gaining more time on Toni Clark and steadily building her advantage.

With four stages complete, fatigue is real. The coastal humidity has been replaced by exposed climbs and rolling farmland. Every step now carries the weight of the days before.

The Boruca region of southern Costa Rica feels different from the postcard version of the country. This is not manicured resort coastline or dense jungle trails pressed flat by tourists. It is rural, working land, shaped as much by history as by weather.

The Boruca people, one of Costa Rica’s remaining Indigenous communities, have lived here for generations, known for their hand-carved masks and fiercely preserved traditions.

Around their villages the land rolls outward into open pasture and patchwork farmland, where cattle graze on steep green hills and small family plots cling to uneven slopes. The terrain is restless. Long climbs rise without rhythm, dirt roads bake under the sun, and sharp descents cut down into river crossings and humid low pockets before rising again.

It is a landscape that looks soft from a distance, all green folds and misty ridgelines, but up close it is rugged and unforgiving. The soil can be loose, the heat heavy, and the gradients relentless. In the high farmlands near Palma Norte, you move through open exposure rather than forest cover, feeling the scale of the land around you. It is beautiful, but it demands respect.
