The Tunnel Race Series was established in 2007 and continues to offer a full marathon
and half marathon on one of the most scenic courses in the country.
Marathon

* No 5-minute Boston qualifying penalty

The marathon course heads east on the Palouse to Cascades Trail to the 6.55-mile

enjoy 10 miles of stunning scenery, including sweeping views, waterfalls, and a gradual
1,000-foot elevation loss to the finish.
Half Marathon
