Spartan H3X : Hurricane Heat endurance event
Spartan H3X is a three-stage Hurricane Heat endurance challenge held at Riverside Farm, 105 Tweed River Dr., Pittsfield, VT on June 26-27, 2026. The event structure allows participants to progress through successive time tiers that together form a full 24-hour challenge.
Participants pre-register for one of three options: 4 Hour, 12 Hour, or 24 Hour. Stage 1 is the Hurricane Heat (4 hours). Stage 2 extends the event to 12 hours with an additional 8 hours after Stage 1. Stage 3 completes the full 24 hours with an additional 12 hours after Stage 2. Participants may continue beyond their registered stage up to the full 24 hours; any advancement beyond the registered tier may incur an upgrade fee charged after the event.
The 24-hour registrants who do not complete the full 24 hours are not eligible for finisher items and will not receive a refund. The published race details list the event duration as 24 hours, an entry age requirement of 18+, and more than 40 challenges included in the course. Team registration is presented as the only way to secure the same start time for a group and to receive group savings when tickets are purchased together or via a referral link after purchase.
A service member discount of up to 25% is available to eligible U.S. military, law enforcement, firefighting and first responder professionals, and certain U.S. government employees via GOVX verification. Visit the organization's website for the most recent information.
