EOD Warrior Holiday Dash Marathon

The EOD Warrior Holiday Dash Marathon in Washington takes place in December 2026 on a flat to gently rolling road course that won't punish your legs, making it a solid choice if you're chasing a time goal or testing your fitness before year's end. The low elevation throughout the race, hovering just above sea level, means you won't be fighting altitude, though December weather in the Pacific Northwest brings typical rain and cold that you'll need to prepare for. This full marathon supports a meaningful cause and draws a community-focused crowd, so expect the atmosphere to feel purposeful rather than purely competitive. The relatively modest elevation gain for a 42.2k distance means pacing and fueling strategy matter more than raw strength on climbs, so focus your training on steady aerobic work and practicing your race-day nutrition on long runs.
