The middle of October brings a strong mix of fall racing, with trail runners getting plenty of reasons to head into the woods. From the Portland Trail Series to Silver Falls, Rogue Gorge, and Elk-Kings, there are several options for runners looking to trade pavement for dirt, along with a good collection of 5Ks and 10Ks around the region.
Sunday brings a few bigger road-racing options, including the Columbia Gorge Marathon and Half, while the rest of the weekend keeps things spread across Oregon and Southwest Washington. This is really the heart of fall running season, when the temperatures can be just about perfect for racing — provided Oregon’s rain stays away long enough to let us enjoy it.
