Leave the start line and go north east. At .66 miles is first course marshal – sends them to the RIGHT which is the FIRST FINGER.

At 2.86 is first WATER STATION at the E County Line road and Quicksilver – in the trailhead parking area on the east side of the County Line Road.

Continue to Sandstone Ranch Nature Center area (not running into parking area) and turn around.  On the way back, encounter the water station again – it is now mile marker 6

At about 8.3 miles, runners are back to the first marshal at the JUNCTION.  A second water station is placed just north of the creek at this Junction.  Energy gels are available at this station.  Racers turn RIGHT – NORTH which is the SECOND FINGER that goes to Shoes and Brews.  (Mile 9.58) and then come back to the JUNCTION. Which is now Mile 10.86 where runners will see a water station for the 4th time.

From the junction, runners head back toward the finish line.  Runners do NOT turn left to cross the trail to the finish (at mile 11.37) , but complete one last finger, heading WEST before turning around at mile 12.16 at the entrance to Kanemoto Park off of Missouri Ave.  THEN turn around and run back to the finish.  The right turn to the finish is at mile 12.96.

5k Runners will leave the start area and run north east.  A water station will be encountered just before the turn around of the first finger (.75 miles).  Turn around at the first turn around and return back (southwest) as if you're going to the start line.  Rather than turning LEFT to the start line (mile 1.35) , continue straight west to the final turn around at Kanemoto Park.  There is a restroom at this park where you turn around at approximately mile 2.15.  Then return to the start line (run east and then south to finish.)
