Tomorrow morning a seething mass of brightly coloured T-shirts, Lycra and sweaty bodies will inch its way around Lake Rotorua in the 50th running of our famous marathon.
The hardy souls chasing the opportunity to cross one more item off their bucket list will have (or should have) put in thousands of hours of preparation for the big day.
Tendons and muscles will have been teased into giving just that little bit more each time, fluid intake will have been ramped up to cater for the amount about to be lost (listen carefully and you'll hear it all sloshing round as the race starts tomorrow) and the credit card will have been given a serious workout as shoes, anti-inflammatories, special nutrition bars and the like are purchased in the hope their marathon goes smoothly - by which I mean they make it across the finish line without looking like they've been dragged through a hedge backwards.
But while countless words have been written about the runners and walkers and their preparation for their big day - and rightly so: it's a huge achievement - spare a thought for those who will be watching the event.
It's not as easy as it looks. In fact, I would suggest the preparation required for spectators can be as intense as that of the entrants.
