In this stage only, if the contestants fall in the water they can still carry on, they just have to go back to the start of the obstacle they just fell off to try it again.
1) Odysseys:
A round platform that rocks and tilts. This has to be crossed to get to the next part of the course.
2) Pipe Slider:
Holding onto a pipe the contestants have to slide down a rail and drop off onto a mat floating in the water below.
3) 'W' Wall:
Here there are two walls that need to be climbed over, and then a ladder to climb to get up a third wall. The first wall is half the size of the second one.
4) Raft Slide:
Contestants have to slide down a tall slope on blow-up dinghies. At the bottom of the slope is a pool of water. They have to stay in the dinghies and float across this water to the next part of the course.
5) Year 5 Maths:
Two numbers appear on the screens in front to the contestants. They have to add the two numbers shown together and enter the answer into the keypad to continue. If they get the answer wrong another sum will show up. They can't move on until they've got one right.
6) Underwater Nets:
Here there are two nets half in and half out of water. The contestants have to swim under both nets to advance.
7) Mast Bridge:
There's a pool of water in a big gap in the course. To cross this gap the contestants have to put a big heavy pole into place to make a bridge.
8) Final Slopes:
To end the course there are two steep slopes that need to be climbed to get to the button, to stop the clock, at the top. The slopes are above each other, with a flat step in-between.
1) Path of the Hammers:
The contestants have to walk across a long balancing beam over the water while along the way there are 20 giant swinging hammers to knock them off. The hammers are in three sections, the first and second sections have seven hammers each, and the last section has 6. If they manage to dodge the hammers and get all the way to the end the contestants must hit the button to stop the clock.
1) Castaways:
There are giant balls hanging from tracks in the air. The contestants must hang onto these balls to slide along the tracks over a pool of water. Once at the other side of the water they have to let go and fall onto a net.
2) Swing Mast:
Here the contestants have to throw the end of a rope over a bar in the air and try and get it to wrap around. If it's wrapped around securely enough then they can use it to swing over the water and onto the next bit of the course.
3) Horizontal Rope:
This is a rope that is tied horizontally over the water. The contestants have to make their way across it without falling off.
4) Cannonball Run:
To cross some more water the contestants have to run over four big balls suspended on swings. The balls also spin round when trodden on to make it even harder.
5) Final Pole:
Lastly, to get to the button to stop the clock, the contestants have to climb up a vertical pole.
1) Final Viking - Celebrity Version:
The contestants have to get to the top of the tall scaffolding tower by climbing up the metal grid on the side. Once at the top they have to hit the button to stop the clock. The contestant who gets to the top the fastest wins.
