Spring Fling Trail Run

Spring Fling Trail Run is held in Alsea, Oregon, on March 6, 2027, in the forests of the Coast Range. Three distances share the day: a 21 km trail race of roughly 13 miles, a 10K and a 5K. All of them run through dense, green timber well away from any town, on the rolling terrain that is typical of Oregon forest land.

This is trail running rather than road racing, so pace targets matter less than time on your feet. The 5K works as an entry point if you have never raced off pavement, while the 21 km asks for real climbing legs and comfort on soft, wet ground in the damp climate of the Pacific Northwest. A sensible build is eight to twelve weeks with one long trail run each week, some hill repeats, and a few sessions in the shoes you plan to race in.
