2026 Spartan H3X
The Spartan H3X is a tiered endurance series held at Riverside Farm in Pittsfield, Vermont. This event is structured as a three-stage endurance challenge rooted in the Hurricane Heat format. Participants must be at least 18 years old to enter. The event is non-refundable and non-transferable.
The challenge consists of three distinct stages that progress in duration:
- Hurricane Heat (4 hours): The initial four-hour endurance stage.
- Hurricane Heat 12 Hour: A second stage lasting an additional eight hours.
- Hurricane Heat 24 Hour: The final stage lasting an additional twelve hours.
Participants pre-register for a specific tier but have the option to continue through subsequent stages up to the full 24-hour duration. Individuals who advance beyond their initial registered tier are responsible for paying an upgrade fee after the event. Finishing the specific tier for which a participant registered is a prerequisite for receiving finisher items. Those registered for the full 24-hour challenge must complete the entire duration to be eligible for finisher materials.
The event features over 40 challenges throughout the course of the three stages. Group registration is available for those wishing to coordinate participation with others. Certain service members, including military, law enforcement, and healthcare professionals, may be eligible for registration discounts through a verification process.
