Start times:

50K solo 8:00am

**This is an ODD year-the course is run in reverse**


The course is 50-kilometers point to point (31.07 miles) from Midvale to Council, Idaho along the scenic Weiser River Trail. The trail is a railroad bed that has been converted to a National Recreation Trail. The trail surface consists of stony railroad ballast, dirt, and some paved crossings as you come into towns. The trail runs alongside the Weiser River, through canyons and across open farmland. There is very little elevation change on the course. The course is ideal for this early season event and excellent for runners of any ability – beginners to veterans. In addition to the solo 50K, we also have a 50K relay.  So no excuses not to run it!  The Relay is open to teams of runners from 2-5 people.  If you plan on fewer than 5 people on your relay-contact the RD before registering for a pro-rated registration per number of people running.

**New Category added: Adaptive athletes this course is ideal for hand cycles, trikes or two wheelers!  Since this is a late addition to the race we will keep the price at the intro price, I really want to grow this category and create opportunities for adaptive athletes to compete!  As this category grows we will add to the depth of the awards, just hoping to kick up some interest!
