For those of you who aren't Harry Potter fans, Quidditch is a wizard sport played on broomstick that has been modified for us non-flying people and is now pretty popular (Quidditch World Cup is coming up on November 12th-13th in NYC). In Harry Potter, a Quidditch Game ends when the Seeker catches the flying Snitch. In the modified muggle version, the Snitch is played by a person who isn't a part of either team, and his/her goal is basically to run away from the Seekers.
I found this article about training tips for Quidditch positions, but all it says about training to be a Snitch is to try cardio kickboxing, and that cross country runners are ideal candidates. How else could I train to build up my speed so that I can run away from the Seekers for a sustained period of time?
