TotalEnergies Bilbao Night Marathon

This November 2026 night marathon in Bilbao runs 42.2km on trail through moderately hilly terrain, so expect a physically demanding race rather than a fast course. The elevation profile is forgiving in absolute terms, but the rolling hills will demand steady pacing and strong legs, especially in the later stages when darkness and fatigue compound the difficulty. Trail footing means you'll need good foot placement and ankle stability throughout, and the night timing makes this a technical affair where headlamp choice and visibility matter as much as fitness. Check the race website for exact start times and course markings, as night running on terrain requires more attention to logistics than road marathons. Train on similar surfaces and practice your night running setup well before November, because this isn't a course where you can coast on base fitness alone.
