Guessathon

 You will be given a point to run to (and back from) and have to guess how long it will take you. The winner is the runner with the most accurate guess. – No watches etc. can be used. Winner is the one with the most accurate guess, not the quickest!

You can start at any time between 18:30 and 19:30, but please don’t come late if you are a very slow runner.
