Athlete Information

One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin. He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divid.

Get Involved


Setting up a big event like the Mercuryman Triathlon takes a lot of work, and the work is not finished when the gun goes off on race day! The event organizers need a lot of help from the community to make the Mercuryman Triathlon a safe and successful event. So if you are not racing or racing as part of a relay, we could use your help!

  • Pre-race Registration & set up
  • Water safety & athlete counters
  • Bike & Run Course Marshals and Aid Stations
  • Transition area security and directions
  • Finish line
  • Athlete Food tent

All volunteers will receive a tshirt and a free post race meal. All of our volunteers will also be entered into a random draw at the end of the race and have a chance to win some great prizes.

Please let us know if you are interested in helping out.
