We started at the spot where, at the world champs, two teams will go head to head down the river. With two rafts on a narrow river, the start is crucial and while it isn't exactly Formula 1 (their words, not mine) it's surprising how quickly the raft picks up speed from a standing start.
The home river advantage will be huge for this team as knowing the best lines to take through each section of the river is crucial. However they tell me the river is always changing and even locals can misjudge it.
The 7m waterfall is not part of the world champs but, to get to the start of the time trial course, we need to go down it. But first, four of the six guys get out. As Nick explains, they don't want to risk any injuries at this stage.
Nick and Paul take me over the waterfall. I think I scream like a girl. I think I close my eyes. There was a lot of water and just as I thought the raft was flipping and I was reminding my panicking self not to panic, up we popped. The raft was upright and I was still in it. Burn marks on my hands from holding on for dear life but otherwise all in one piece. Awesome - can we do it again?
Then back to business. The time trial will be the first of the four disciplines held at the worlds - it and the Head to Head are on the Kaituna, the Slalom is on the Tarawera and the Down River on the Rangitaiki. The time trial takes us about two and a half minutes. It doesn't sound a lot, but at the end these six fit men are breathing heavily - they go hard out.
Fun time over for me but it was back to the start for the team, to do it again and again.
Around 5000 people are expected to converge on Rotorua and Kawerau for the champs, which run from November 13 to 24. Spectator viewing points are planned.
Oh and if you haven't done it yet, go rafting. It's beautiful, exhilarating and not as scary as it sounds - apart from the wetsuit bit.
