|Getting There:||To reach the south trailhead, take Broadway south out of Boulder and turn off onto Marshall Road. Park along Marshall Road and start your run inside the gate at the trailhead. The north trailhead is on Baseline about 200 yards west of Cherryvale Road.|
One of the few mostly flat running trails in Boulder, Bobolink/South Boulder Creek Trail stretches for 3.3 miles between Marshall Road and Baseline Road. (It slopes slightly downhill from south to north, dropping 130 feet from trailhead to trailhead.) It’s a great place for recovery runs, tempo runs and interval workouts. You can tack on additional miles by continuing under the Baseline Road underpass and linking Gapter Road, a path along South Boulder Creek and Old Tale Road to Arapahoe Avenue, where you can then connect to a spur of Boulder Creek Path. If you’re training for a marathon and need to run a long run without much elevation gain, it’s easy to link trails and paths for a 16- to 22-mile run.
