Some of New Zealand's best multisport athletes are expected to take part in this year's Ecomist Blue Lake Multisport Festival on Auckland Anniversary weekend.

It's one of New Zealand's longest-running triathlon and multisport events run by Rotorua Association of Triathletes and Multisporters (RATs) and held at the beautiful Lake Tikitapu on January 30-31.

The event has long attracted interest from up and coming New Zealand triathletes, and this year the field is expected to be no different.

One of the latest 'name” entries to the event is Clark Ellice, who between 2008 and 2013 represented New Zealand on the international ITU triathlon circuit.

Also expected to be at the event is Commonwealth Games 2006 silver medallist and Olympic representative Samantha Warriner.

Samantha recently retired from professional racing, but has been a big supporter of the event for a number of years, bringing with her a number of young age-group representatives from her Sweat7 coaching squad.

The weekend covers a range of events including the Physiotherapy Clinic Aquathon (5.5km run and 800m swim, the Meat Shoppe Kids Triathlon (open to kids 5-12 years of age), the YHA Open Water Swim (750m and 2km options) – part of the Famously Rotorua Swim the Lake series, the Cyclezone Sprint Triathlon and the 5.5km Fun Run/Walk.

Event director Nicola Muggeridge says the great thing about the event is there is something for everyone.

'Whether you are an elite triathlete or someone who just wants to give triathlon or multisport a go, there are options to suit everyone.

'We are extremely lucky to be able to host this event for its 30th running at the spectacular location of the Blue Lake,” Nicola says.

'This year we expect to see an increased field of competitors, in particular for our Kids Triathlon. It's great to see each year this relatively new addition to the event keeps growing and means triathlon is approachable for all ages.”
