The Kaikoura New World Duathlon has a 5km fun run/walk event, as well as the run-cycle-run duathlon main event and children's duathlons.
The course is described as the most scenic in New Zealand. Where else can you do a duathlon / fun run and have a good chance of spotting whales, dolphins and an abundance of seals.
The 5km course follows the same route as the run section of the duathlon, just starting 200m short of where the Duathlon runners will. This course offers an uphill and a fast downhil.
