Longview-Kelso, WA

The twin cities sit where the Cowlitz and Columbia rivers meet, offering mostly flat terrain ideal for distance running and cycling. The R2L 10K Bridge Run crosses the I-5 bridge between Longview and Kelso, while the 160.9km Columbia Century Challenge is the region's signature cycling event, rolling through the nearby Columbia River gorge with modest elevation gains. Local runners use the riverside paths along both rivers, and cyclists head east toward the Cascade foothills for steeper terrain within 30-40km.
