An endurance backyard run in the Hrazdan Gorge where the challenge is endurance rather than speed. Format: Every hour, participants start a new 4.2 km loop. If you finish before the hour ends, you can rest and refuel, but the next loop starts at the top of the hour. Anyone who fails to finish a lap within the hour or misses the start is eliminated. The last remaining runner wins. If multiple runners make it to the 24th loop, the first to cross the finish line wins. Those who prefer not to run the full 24 hours can join any start as a guest and run one or several laps outside the competition. • Main race entry: 5,000 AMD; guest race: 1,000 AMD • Age limit: 18+ • Water, start village, and medical staff on site • A headlamp and reflective elements are required for running at night Registration: via the link in the organizer's Instagram profile.
