Course Maps

Marathon (26.2 Miles), All runners will start at the Boulder Beach picnic area. Start with a gradual quarter mile climb until you turn right onto the River Mountain Loop Trail. 10K and 5K runners will cover rolling terrain until they reach their respective turnaround point, where they will retrace their steps back to the finish line. For Marathon and Half Marathon runners, the next few miles are a series of rolling paths and flat sections. Then a 1 mile long uphill climb that will lead to your first turnaround. You'll continue with another 1 mile downhill. Then miles 6.7 to mile 10 are a Loop Trail for a slight gain in elevation. At mile 10 continue straight, running past Boulder Beach. Climb 1.5 mile uphill, going past the entrance of the park before reaching the 2nd turnaround. Head back for 1.75 miles downhill, taking a right at mile 12.8 back to Boulder Beach's finish line. All marathon runners will complete 2 laps of this course. You will see the turnaround on the same road you started on. Do not veer into the finish line on your 1st lap.
