Go Big returns to Hilo, Hawaii on December 31st, offering extreme long-distance races that challenge even the most experienced runners. The event is organized by Hawaii Mountain Running with a focus on supporting local wildlife conservation through proceeds benefiting the Hawaii Wildlife Fund. Participants can choose from several distances including a grueling 260 Miler and a more manageable yet still demanding 50K run.
The race starts at dawn, specifically at 6am sharp in Volcano, where runners will face firm but slightly soft trail conditions throughout their journey across parts of the Big Island. The atmosphere on December mornings is cool with an average temperature ranging between mild highs and chilly lows, making for a brisk start to the day as participants gear up early before heading out into the wilderness.
Go Big has been held annually since its inception at local runners' request, aiming to foster endurance among athletes while raising funds for environmental causes. The race attracts dedicated runners who are eager to push their limits on New Year's Eve with distances that range from 50K all the way up to a staggering 260 Miler distance option. Each year sees growing participation and community engagement as more people take part in this challenging event.
The Go Big course winds through rugged terrain, offering runners an immersive experience across various parts of Hawaii’s Big Island. The race venue is located near Volcano National Park, with the starting line at Cooper Center on Wright Road. Runners will encounter firm trails that can become slightly soft underfoot during their journey, making gear choices and pacing strategies critical for success.
Weather conditions in December are expected to be mild but variable; temperatures range from cool early mornings around 7am up to warmer daytime readings later in the day with an average UV index of low exposure. The trail is well-lit at dawn, ensuring visibility despite cooler morning temperatures which can drop below comfortable levels as participants begin their journey.
The race offers a variety of distances including a demanding 50K run and even more ambitious options like the daunting 260 Miler that stretches over hundreds of kilometers across some of Hawaii’s most challenging terrain. Each distance is designed to test runners in unique ways, providing both experienced ultrarunners and new challengers an opportunity to set personal goals.
