  Top of Tamarack is where mental health meets mental strength, all for a good cause!

  This is an event unlike any other! Participants run, hike, or bike up the mountain and soak up the epic views of Valley County! You can choose to tackle any distance along the service road leading up to the summit. The maximum distance is 15 miles round trip with a full 2,900 foot elevation climb to the Top of Tamarack. There is no DNF (did not finish) in this race. Each mile post along your journey will be marked with a special token, reminding you that you have achieved a great distance and you are “mentally strong.” Collect as many tokens as you can and then head back down the mountain to celebrate your achievement. The first male and female to reach the top (for both biking and running) will be crowned King and Queen of the Mountain!

  Top of Tamarack is a suicide awareness and mental health recovery event. It celebrates those who are battling mental health challenges on their way to mental health recovery and who are still here with us today. It is a race that honors those who have lost their lives to suicide. It is a race that brings together athletes of all levels and gives them a purpose for moving forward. Race proceeds will benefit Gr8ter, Inc., a local non-profit organization that helps people struggling with mental health issues find hope and happiness through movement, connection, and purpose.

  You must register by September 1st in order to be guaranteed race swag.
