The Tarawera Ultramarathon started six years ago.
"It was really a crazy dream to start with," Charteris said.
"These days we sell out well ahead of race day with a big waiting list but it's still unbelievable to think that hundreds of the world's running media will be in a press conference in France learning about the Tarawera Ultra."
Charteris said the Ultra-Trail World Tour was all about bringing runners together in the spirit of friendship, adventure and competition.
Other races on the tour are the Western States 100 Mile Endurance Run (USA), the Marathon des Sables (Morocco), The North Ultra-Trail du Mont-Blanc (France, Italy, Switzerland), The Transgrancanaria (Spain), Lavaredo Ultra-Trail (Italy), Vibram Hong Kong 100 (Hong Kong) and the Ultra-Trail Mont Fuji (Japan).
"These are all successful, well-established events with long histories, big race fields and massive media interest," Charteris said.
"And they aren't just about the racing they're also about the magnificent landscapes and exotic environments they're run in."
It will be an opportunity to showcase Rotorua and New Zealand to the world, Charteris said.
