The sun is barely up and pixel Jordi Wild is already lacing his boots. Today's challenge is the Scree Slope Sprint, a punishing trail of loose stones that climbs from the valley to the ridge, and he wants to reach the top before the morning mist burns away.
The path is anything but kind. Rocks roll across it, fallen logs block the way, icy streams cut through it and eagles swoop low over the slope. Running costs energy, and every jump costs a little more, so the water bottles left along the trail by other runners are worth their weight in gold. Pace yourself, keep drinking and see how high you can climb.
