Ultra Trail Bosques del Sur 2026
Recommended gear
Mixed terrain of forest trails, technical sections and some tarmac. The late-May heat in Jaen is a key factor to consider.
Trail shoes, hydration vests, trekking poles, waterproof jackets and the rest of the gear you need. Every recommendation is tailored to the race's specific terrain: high-altitude scree in Sierra Nevada calls for very different shoes than a forest trail in the Basque Country.
