Chris and Paul drive 11 laps
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Chris and Paul kept driving past the new rules, so had to keep making a u-turn, one of which caused the ducks in the back of the cart to fall off. This meant that they had to keep turning by the caravan to retrieve ducks, at one point crashing the cart into the caravan. They completed the 11 laps in 11 minutes and 27 seconds, but they broke 15 rules, so their final time was 36 minutes and 27 seconds, receiving 2 points each.
