Due to it being a long task (4 hours) and some people being away I didn't get any other Goodgymers to join me for marshalling the Cancer a Research Pretty Muddy event on the Knavesmire. When I got there they paired me up with another marshall on the Wall obstacle near the end of the course. After a bit of a wait for the first of the kids to come through there was then a steady stream for nearly 3 hours with the different waves of the kids and adults races. The main task was to stop there being more than one person on each wall at a time and to get help if there was a problem. We were given a radio and there was a constant stream of info about which groups were setting off and arriving at or through different stations. Although our obstacle didn't involve water or mud most people arrived very wet and muddy which made the wall a tricky challenge for some participants.
