Ohm Trail: The Harshness of the Ardennes

Documenting the Ohm Trail requires capturing both the grueling environmental challenges and the raw agility of the athletes. To tell a complete story at one of the course's most technical river crossings, I deployed a remote dual-camera system. My primary setup—an EOS R6 Mark III paired with the RF 24-105mm f/2.8 L IS USM Z—allowed me to track the runners head-on, isolating their intense focus as they approached the water.

Simultaneously, I wedged my secondary camera (an EOS R6 Mark II with an EF 16-35mm f/2.8) into a narrow gap between two boulders on the left flank. To guarantee absolute sharpness for this remote trap shot, I pre-focused at an ultra-wide 16mm and stopped the aperture down to f/5.6 to maximize the depth of field. To completely freeze the runners' rapid movements over the obstacle—and, crucially, to suspend every explosive water splash and airborne drop in perfectly sharp detail—I pushed the shutter speed to a crisp 1/800 sec. This required bumping the ISO to 1000 to compensate for the exposure under the dense forest canopy. Triggered remotely, this extreme low-angle perspective captured the raw athleticism required to navigate the river, freezing the athletes mid-leap against the slick, jagged terrain.
