South Bay 24

South Bay 24 is a timed endurance event held at Montgomery Waller Community Park in San Diego. The 2027 edition is listed for July 23, 2027 and marks the event's sixth annual running. The main course is a 1.22 mile loop that combines trail, grass, and bike path surfaces and gains about 56 feet per loop. The loop is run counter-clockwise.

The course surface breakdown is approximately 50% trail, 25% grass, and 25% bike path. The course is generally flat with a couple of small hills. Completing 82 loops equals 100 miles on this layout.

Race options include:

  • 24 hour event
  • 12 hour night and 12 hour day options
  • 6 hour day option
  • HEFFTY Half Marathon night (13 laps)
  • South Bay Social and shorter social options

Support and amenities include an on-course aid station staffed throughout the event offering water, electrolyte drinks, and snacks during designated windows. Additional features at the venue include a dedicated runner campsite area, a pancake breakfast for participants, finisher medals for all finishers, and a belt buckle awarded to those who reach 100 miles.

A shorter South Bay Social session provides a relaxed morning of trail miles and a finisher medal without awards, and it is limited to 50 runners. The course record is listed as 103 laps (125 miles) set in 2026. Visit the organization's website for the most recent information.
