PRX is a casual running group that meets for casual runs in the Presidio. Courses and lengths vary, between 4-6 miles. All running abilities are welcome. We've got individuals ranging from former high school athletes-gone-soft, to fashionable-fitness-fad-freaks, to weekend warriors, to marathon junkies, to Ironman triathletes.
