TRIATHLON - DUATHLON
TRAIL RUN
The Sea 2 Sky Challenge is a unique multisport event based in Christchurch, New Zealand, offering athletes a range of exciting and scenic challenges.
The full challenge features an ocean swim, a demanding hilly bike ride, and a spectacular run. Duathletes complete the same course but replace the swim with a flat run.
The run challenge is a 16km loop that begins with a climb up to the Summit Road on the Captain Thomas Track, before traversing the Crater Rim Track with stunning views over Lyttelton Harbour. The route then joins triathletes and duathletes on the Godley Head and Taylors Mistake tracks.
For newer participants, the Tri A Try/Du events provide a shorter, friendlier option, while younger athletes can take part in the junior race.
Finally, children aged 5–9 can experience the fun of multisport with a kids’ aquathon (swim/run).
All events, except the kids’ aquathon, can be completed either individually or as part of a team.
