Oakmont junior Karlie Garcia and Vista del Lago sophomore Clare Carroll enter Saturday's Foot Locker National Cross Country Championships in San Diego knowing well the race's three-mile Balboa Park course.
Garcia, who won last Saturday's West Regional girls championship at Mt. San Antonio College in Walnut, placed 15th at the nationals in San Diego in 2009.
Carroll, who finished eighth in the regionals last Saturday, placed 30th on the same Morley Field course in the 2010 nationals when she ran for Granite Bay.
A top 10 finish by either Saturday would be the best for an area girl since Ponderosa's Jen Schindler placed eighth in 1996.
