The event called Airfield Anarchy will take place on Saturday, March 22, at RAF Winthorpe in Newark.
A total of 1,500 runners will tackle miles of muddy terrain and clamber over 30 obstacles including walls, monkey bars and rope swings.
There will also be a parachute display, fireworks, a World War II battle re-enactment, hog roast, live music and weekend camping.
Funds raised will go to the RAF Benevolent fund.
Registration will begin at 9.30am. The first wave of runners sets off at 10.30am.
