Triathlon - a discipline consisting of 1500m swimming, 40km cycling and 10km running - made its first Olympic appearance at Sydney 2000 and has been part of the programme even since.
Great Britain and Switzerland have won two gold medals each, with Brit Alistair Brownlee winning the last two men's titles, beating brother Jonathan into silver at Rio 2016.
As well as the men's and women's individual races, Tokyo will see the addition of a mixed teams event, consisting of two men and two women over a short course (300m swim, 8km cycle & 2km run).
New Zealand enjoyed one of its finest Olympics moments at Athens 2004, when Hamish Carter and Bevan Docherty battled for the men's crown, with Carter eventually prevailing. Docherty returned four years later to capture bronze at Beijing.
This time round, our best medal chance probably lies with the team event, where New Zealand finished third at the 2018 Commonwealth Games, behind Australia and England, and won the world U23 title the following year.
