The Chupacabra Endurance 10-hour Run, hosted by the Crazy Legs Race Series, offers a thrilling and distinct challenge for ultrarunners on August 29, 2026, in Westville, Indiana, at Bluhm County Park. This 10-hour timed event dares participants to complete a demanding 4-4.2 mile loop within a strict one-hour cutoff for each circuit. Fail to meet the hourly pace, and you're "ousted" from the race, making every step count. Typical race day conditions in late August bring highs around 80°F and lows near 57°F, with a 14% chance of precipitation, setting the stage for a true test of grit and adaptability.

The course itself features a challenging mix of pavement and winding single-track trails, with "lots of hills" and "roller coaster hills" that will push your endurance to its limits. A single aid station, conveniently located at the start/finish area, provides essential hydration with Gatorade and water, along with various snacks to fuel your efforts. Runners are encouraged to bring any specific personal nutrition needs, and ample crew space is available at the shelter, allowing for personalized support throughout the event.

Beyond the unique hourly cutoff format, the Chupacabra Endurance 10-hour Run rewards perseverance with a limited-edition t-shirt and a distinctive wooden Chupacabra medal for all finishers. The race employs a unique prize system where participants earn colored poker chips for completing a certain number of loops, which can then be exchanged for items ranging from past Crazy Legs Race Series merchandise to gift cards and even free entries into future events. A thrilling cash pot also awaits the overall male and female winners who conquer the final loop. This event is a captivating part of the Cryptozoology Race Series, offering an additional raffle entry for a gift card to those who complete the Chupacabra along with its companion races, the Yeti and Bigfoot events.
