About the PZ Backyard Ultra

PZ uses the backyard start-and-restart rhythm but caps the competition at 48 hours. Runners leave Hotel del Sur at sunset for a 6.706-kilometer loop every hour, with 48 yards equaling 200 miles.

Course

The organizer describes a 6.706-kilometer asphalt-and-gravel yard with about 50 meters of climbing. The hourly corral rule applies throughout, but the race ends after 48 completed loops if it has not ended earlier.

Race-day weather

January falls in the region's comparatively dry season, but afternoons can still be warm and sun-exposed. The evening start reduces early heat before runners cycle back into daytime conditions.
