The Tough Mudder is very impressive for me by its motivations of all participants. Unlike the relax atmosphere at Noosa Jazz Festival, the day I attendant in Tough Mudder was a very busy Sunday with over five thousands of attendees in that day. My first job was cheering people up in the first obstacle, Kiss of the Mud, and it is really interesting experience to me. In most of the event, the volunteers are the boundary spanners of the event organization. So that before I did my job, the volunteer manager told us we should do whatever things we could to cheer people up by encourage them and make some noise. Though our passionate encouraging, people seemed more enthusiastic about competing in the challenges and expecting about the further obstacles.
