Once atop the travelator, contenders then grabbed a rope and used it to burst through a paper barrier to finish. When it was unclear which contender won, producers would watch a replay to determine who had torn the paper wall at the end first. A new version was created for the Sky 1 series, and incorporated an underwater swim in the pool at the beginning. This feature caused contenders to become fatigued sooner, and being wet made some obstacles harder to overcome. As a result, the travelator would sometimes need to be slowed down or even stopped to help the contender finish the course. The order of obstacles in the rebooted series was as follows: underwater swim, cargo net, cotton reel (series 9 only), fireman's rope (series 9 only), floor travelator (series 10 only), monkey bars (women)/hand bike (men), balance beam, pyramid, zipline and travelator. The Wall First appearance: series 1, 1992 – heat 1 Last appearance: series 10, 2009 – “Battle of the Athletes” Contenders attempted to climb up a 36ft climbing wall covered with hand and foot holds while the Gladiators gave chase, and attempted to pull them off. In the first series, the female contenders received a 20-second head-start, falling to 15 seconds in the semi-finals and final; while the men received a 15-second head-start falling to 10 seconds in the semi-finals and final. In later series, the head-starts were standardised at 10 seconds for female contenders and 7 seconds for the male contenders. In series 1 and 2, contenders received 10 points for reaching the top of The Wall, from series 3 to 8 this was changed to 10 points for reaching the top first and 5 points for reaching the top second. In series 9 and 10, contenders could also score 5 points if they remained on The Wall at the end of the 60-second time limit. If the contender fell off The Wall before the Gladiator was released, they were allowed to try again. However, if the contender fell after the Gladiator started climbing, it would be a loss. The Gladiator was allowed as many tries as necessary. A win was only counted if the contender got their entire body over the wall within the time limit. Contenders were not allowed to try and remove the Gladiators or their opponents from the wall. Gladiators were forbidden from touching the contenders' harness equipment or necks.
