Ruth McKenzie Preserve Half Marathon | 10k | 5k | Kids Race

🏞️ Race Overview

The Ruth McKenzie Table Mountain Preserve (2960 acres) is located between Friant and Prather, on the north side of Auberry Road. The main gate is 3.3 miles uphill from the intersection of Auberry Road and Millerton Road.

🌳 History of the Preserve

The McKenzie Preserve was acquired in trust from The Nature Conservancy in 1998. The property had previously been placed in a trust by its owner, Ruth Bea McKenzie, who wanted it to remain in ranching and open space after her death.

🌼 Natural Features

• Landscape: The McKenzie Preserve is primarily grassland and oak woodland that slopes upward toward the basalt lava table lands that give the preserve its name.
• Vernal Pools: In spring, rain water collects in the table’s low spots, forming vernal pools that provide habitat for rare plants and crustaceans.
• Wildlife: The pools hold water for several weeks or months until it evaporates, allowing crustaceans to survive as seeds or cysts during dry periods.
• Forested Areas: The north-facing slopes sustain an excellent mix of pine forest and chaparral.

🌊 Additional Features

On the far side of the table formations, out of sight of Auberry Road, the land slopes steeply down to the San Joaquin River. The preserve also includes a 47-acre parcel along the creek on the south side.
