Welcome to the ULTIMATE running quiz! Running Channel presenters Anna and Sarah go head to head for a hefty cash prize of £1000. Whoever stops running last walks (or runs) away with the prize money.
But there is a catch. They have to start off at half marathon pace on the treadmill and answer general knowledge questions, with forfeits along the way. For each question they get right the other presenter has to put their speed up by 1 kilometre an hour, but if you get a question wrong, your speed goes up by 1 kilometre an hour.
Last person to stop running wins. Who will be victorious? Keep watching to find out!
