With four ugly-sweater races kicking off December last week, the festive fun is already in full swing—but the following weekend keeps the momentum going with a diverse slate of events across Oregon.
Runners can head into the woods for a true trail challenge, lace up for a long-standing South Coast classic, jump into a fast and friendly 5K race series in Beaverton, or take on Portland’s famed Holiday Half Marathon—the marquee event of the season.
