The challenge is on but will help families in the Magic Valley. It’s the “Rim 2 Rim” run and it goes from one side of the Snake River Canyon to the other over the Perrine Bridge. The race is competitive and is 7.5 miles and you can still register. If you want less of a challenge you can do the half rim run which is mostly downhill. The cost is $45 per person or $25 for the half rim. To register you can come by the Restore location for Habit for Humanity in Twin Falls, you can call 735-1233 or you can click here to register on line. The funds raised help build homes for families in the Magic Valley. Five homes are under construction this year and they are looking to help more families next year.
