  • World’s Toughest Mudder at Belvoir, 2025 ↗

    Alan “Muddy Duck” Moore · 2025

    Moore initially wanted more distinctive obstacles, but ultimately praises the course layout, organization and exceptional mutual support. His 65-mile account describes heat, night racing and physical exhaustion.

    Complete first-person 2025 Belvoir report read, including the final assessment. Historical endurance-race experience from one competitor, not a rating of the standard Tough Mudder course. No explicit overall numerical score.
