Hea-van

battle: Our converted Fiat Ducato with a roof platform standing 2.6m high, simple enough when fresh but less so during an OCR race. "Hoorah" if you can get up this alone, without cheating.

Fun: 4 out of 5
Fear: 3 out of 5

The Rubber Tree

rood: chains, ropes and rubber. maybe not just your average sunday afternoon but at over 3m high, swinging in all angles and completely vertical. This one takes more courage than you realise.

Difficulty: 4 out of 5
Fun: 2 out of 5
Fear: 5 out of 5

Floaty McFloat Race

Rood: Definitely a crowd-pleaser. This 50m long stretch of pontoons is the longest in OCR history. Rhythm and courage are vital if you want to avoid hitting the deck or hitting the lake. But even if you find your stride, there's no guarantee...

Difficulty: 3 out of 5
Fun: 5 out of 5
Fear: 3 out of 5

Hang Solo

Rood: This unique hurdle takes a little bit of skill and fore-thought. Scramble up the board to find yourself traversing along a 5m pole with a dismount to finish. Few will do this with elegance and style but that's not really the point.

Difficulty: 4 out of 5
Fun: 3 out of 5
Fear: 3 out of 5
The Daddy Slide

Daddy Slide

Battle: A 40m long water slide down a steep hill with a very wet plunge to finish; smile for the camera if you can stop screaming.

Difficulty: 1 out of 5
Fun: 5 out of 5
Fear: 3 out of 5

Up-The-Chainey

Battle: A 7m high, multi-floor tower with chain ladders, fireman's poles, nets and several levels to descend and climb; a whirlwind OCR skills test.

Difficulty: 4 out of 5
Fun: 4 out of 5
Fear: 3 out of 5

AAA

Battle/Rood: AAA has 3 variations of climbing holds across 3 A-boards which requires you to traverse from one to the other. It's made trickier by tiredness, poor grip strength, mud and impatience. Take your time and be confident of your footing.

Difficulty: 3 out of 5
Fun: 3 out of 5
Fear: 2 out of 5

The Rood Ramp

Rood: this is not your typical quarter pipe, it takes you on a real journey. It starts gently but gets more serious and then bites back with an over-hanging top third. This requires, speed, intelligence and determination. Or a team of strong people.

Difficulty: 5 out of 5
Fun: 4 out of 5
Fear: 3 out of 5
Inverted Walls

Inverted Walls

Battle/Rood: These intimidating overhanging walls stand at 2m high at an angle of 24°; it's entirely possible but maybe bring a friend or two.
