    Epic Endurance Begins: CurraNZ Powers the Grand To Grand Ultra Across the Grand Canyon

    on August 20, 2025

    The countdown is on for one of North America’s most demanding ultra-endurance events, the Grand To Grand Ultra – a self-supported stage race spanning 275km over seven days, across the breathtaking expanse of Utah and Arizona.

    Starting at the jaw-dropping north rim of the Grand Canyon, one of the Seven Natural Wonders of the World, and finishing at the Pink Cliffs atop the Grand Staircase, this race will be an adventure of a lifetime that tests the resilience of every runner who participates.

    CurraNZ is proud to be an official supporter of the G2G Ultra, supporting the demands of athletes in their toughest moments - and a trusted choice for ultra-runners seeking every possible advantage.

    Amidst this year’s international competitors, New Zealand’s renowned endurance athlete and nutritionist Mikki Williden is set to challenge the course this month, powered by CurraNZ.

    Mikki is no stranger to tough terrain and long distances, and we wish her and her fellow runners all the best in the event.
