Swim:  Participants will enter the water at the old boat dock southeast of the bridge.  The exit is at the primary boat dock on the north east side of the bridge.  Swim temperatures average about 45 – 50° at this time of the year and flow can vary widely, from 8600 CFS – 23000 CFS.  The current has been known to change from year to year as well.  

Bike:  The course can run from 13K to 17K, and is altered each year to accommodate water levels. There is some blacktop, but approximately 90% of the course is through the gravel foothill trails northeast of Alpine.

Run: Starting at the substation located on the east of town, the running course winds through the cozy neighborhoods of Alpine, then turns off the road into the trails aside the Greys River. The run course varies from 5.5K to 7K as the course is adjusted for water levels.

* Please note that even these maps may vary some depending on water levels.
