Sunnyside Road for a short distance, then LEFT onto the Greenbelt, then turning RIGHT upon entering South Tourist Park UPPER LOOP to return to transition area.  There is an AID STATION at the Sprint turnaround with only water.

There will be volunteers and police at all major intersections—Use CAUTION on all corners and watch for gravel, cattle, and random farm sprinklers! Again, there will be a minor AID STATION that will have bottles of water only at the Sprint Turnaround.  You will be coached on where to dismount your bike and get ready for your run.

SPRINT RUN—3.14 MILES

The RUN portion of the GREAT SNAKE RIVER TRIATHLON will begin from South Tourist Park transition area Sprint run course out-n-back.  You will exit transition and head north along the scenic snake river greenbelt path until you come to Pancheri bridge on 17th St.  Turn left and head across the bridge and turn left again to go through the tunnel under the bridge to the northwest side of the river path.  Follow the path straight up to the aid station positioned at the restrooms near the SpringHill Suites.  At this point you will turn around and run back exactly the way you came.

We will have volunteers at all major road crossings / loops to guide runners on the greenbelt, once again returning to South Tourist Park and FINISH LINE.  Please be nice to other people using the walking path / greenbelt.  Run hard…there is a FINISHER MEDAL waiting for you after you pass the FINISH ARCH!
