Welcome to the triathlon of colossal vehicles! Kick things off with a briefing, before hopping behind the wheel of a Land Rover Defender 90 as a warm up. Next, take the British-spec monster truck known as 'Black Ice' over some tough, purpose-built terrain and experience a deliberate sideways roll-over in a 4x4 buggy. Then, it's the bit you've been waiting for - clamber up a step ladder to board into the cab of the full-spec, 66-inch terra-tyred American monster truck affectionately named 'Grizzly'. Take a deep breath, then drive this amazing vehicle over the top of two saloon cars (they'll be well and truly wrecked) - steering the beast of a truck on a mission of destruction. It's a pure adrenaline rush
