Course Description:

Oblivion 2020 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.
Complete 3 laps to qualify for the 2020 OCR World Championships age group division
Complete 4 laps to qualify for the 2020 OCR World Championships pro division
Every entrant will wear a personalised running vest, which will enable priority at all obstacles. This event is about your endurance. Oblivion Extreme runners must complete all obstacles. Competitors must have one or more genuine attempts but if continuously unsuccessful a penalty must be taken (eg: sin-bin, carry, extra run). Competitors will be told what the penalty is and how to undertake it at the obstacle. If aiming for qualification for OCRWC or earning points for the Nuclear league you must select the option at time of booking so you are allocated a bib to wear.
The race will finish after 8.5 hours.
You’ll be unable to start a 12km lap after 3pm
We will start clearing the Oblivion course from 5pm onwards (last runner 1st)
