Oblivion 2021 has the potential to be a 60k+/37+mile/450+ obstacle challenge. It’s Nuclear Oblivion EXTREME. Designed to challenge the fastest and fittest obstacle race athletes out there; it’s our most brutal & unforgiving event in the Nuclear calendar.

There’s 8.5 hours to complete as many 12k laps on the Nuclear Rush course tackling 90+ man-made & natural obstacles per lap. This event requires hardcore training as it’s the ultimate test of physical and mental endurance and strength. Entrants are Oblivion Extreme Legends. This is not a team event. Pit Crew welcome.
