The Experience
Judgment Day Half Marathon, first run in 2014 and now in its 12th edition, offers a unique challenge in Bakersfield, California. The course starts and finishes at the historic Sam Lynn Ballpark, taking runners out to the paved Kern River Trail and into the Panorama Vista Preserve.
The half marathon features a 3.5-mile loop on dirt trails within the preserve, followed by a return to the paved trail. A notable feature is the challenging 1-mile climb up to the Panorama Bluffs on a closed road, offering rewarding vista views before a descent back to the finish. The 10K, introduced in 2025, shares the initial paved trail section before a separate dirt trail climb.
With a median field size of around 350 finishers and a growing trend, this event draws participants from approximately 3 states. About 34% of runners return each year, highlighting its loyal following. Runners can expect typical race-day temperatures ranging from 65–92°F.
