JAMBAR is proud to announce a new partnership with Inside Trail Racing (iTR), a California-based organization that creates welcoming, community-driven trail running events across some of the state’s most breathtaking landscapes. From the rolling Marin Headlands to the rugged Santa Cruz Mountains, iTR’s races bring runners together to challenge themselves, connect with nature, and celebrate the joy of running.
This collaboration underscores JAMBAR’s passion for supporting the running community at every level—from trail running newbies to seasoned ultra runners. Founded by runner, nutrition innovator, and co-creator of the original PowerBar®, Jennifer Maxwell, JAMBAR was designed to fuel athletes with organic, real-food energy that tastes as good as it performs.

“Running has been central to my life since I was a young girl, and JAMBAR was born from that same love for movement and community,” says Jennifer. “Partnering with Inside Trail Racing is a natural fit—we support their goal of creating fun, welcoming and well-supported spaces where runners can thrive, push their limits, and have fun.”
Look for JAMBAR at upcoming Inside Trail Racing events including the Woodside Crossover, the Mt. Diablo Trail Run, and the Golden Gate Trail Run, where participants can enjoy on-site sampling and discover why JAMBAR has quickly become a go-to energy bar for athletes who care about clean ingredients to fuel their bodies.
As JAMBAR celebrates this new partnership, the message is clear: great things happen when passion, community, and real food come together on the trail.
