After a disappointing day in the individual races saw Andrea Hewitt the only Kiwi to earn a top-10 finish, the team must show they're greater than the sum of their parts in tonight's (NZ time) relay.
And Sissons, whose 13th in the men's race ranked fifth among the six-strong New Zealand team, will assume most of the responsibility in ensuring the sport avoids a Games to forget.
In previous years, that prospect would already be reality, and the team would be heading home without adding to this country's fine recent record in the sport. But on this occasion, for the first time at either a Commonwealth Games or Olympics, the individuals have a shot at redemption.
The relay has been raced in various formats since 2003, with its current iteration introduced in 2009. As a four-person mixed race, the event has been a fixture at the world championships since 2009, while New Zealand took silver behind the hosts in Hamburg last year.
Replicating that result will depend largely on Sissons because, with each of the team racing a mini-triathlon, the pressure lies on the anchor leg. That means that while many see the event as a light, bright alternative to the full format, Sissons struggles to see the fun side.
