Trail Shoes
Hoka's cushioning pays off in the final hours of an ultra. Budget option: Decathlon's Evadict range offers solid performance for first-timers.
Hydration Vest
Essential for carrying water and nutrition. Salomon vests are popular for good reason, but Decathlon's alternatives do the job at half the price.
Trekking Poles
With 4,656m of climbing, poles will save your legs. Worth the investment for this much elevation.
Headlamp
Check if your race goes into darkness. A good headlamp (200+ lumens) with reliable battery life is worth having ready.
