The Interceptor wouldn't leave contestant Mike alone as he got his key from the top of a factory, but while attempting an ambush, he was spotted by Mike and gave up. Contestant Sarah cycled down from her starting position to get to her key challenge on a river, only to see the Interceptor nearby in a dinghy. Mike and Sarah failed to meet up within the 40-minute time limit, and it turned out that the Interceptor had failed to zap Sarah's backpack — which contained the £1,000.
