TRI Challenge Triathlon



All ages on 31 Dec 2023

  • 400 m lake swimming
  • 20 km road cycling
  • 5 km road running


If taking on the super fun full team challenge, this is how it works. 3 team members each completing all disciplines, however it's a baton handover style event. First team member does the swim, then hands over timing chip to team member number 2 who then does the same and so on. So each team member has a break between each discipline. It really is great fun! If taking on the split team challenge once you decide who is doing what discipline the first team member will swim, then hand over the race chip to the 2nd team member at the handover pen and then the team member biking will do the same thing for the 3rd team member who will finish with the run. If entering the team challenge you must either register your team of 3 and include your team name in the booking or each entrant can register seperately. Make sure they enter exactly the same team name when entering. The atmosphere is fantastic, the event is super fun, friendly and a great laugh with a little bit of competition involved as well!
