About Us

Mountain Biking in the Pacific Northwest

We started doing endurance races years ago, and over time transitioned into organizing endurance events as well, from adventure races, duathlons, trail runs to mountain bike races. In 2010 we had a very successful first endurance mountain bike event, the Capitol Forest 50/100 Miler. The idea was born to promote more endurance events in Washington, now the point series include three races per year, starting with Stottlemeyer 30/60 Miler in May, followed by Echo Valley 30/60 Miler in June, and ending with Capitol Forest 50/100 Miler in August.

Our goal is to provide you with the best course and most amazing support to give you a bike race experience you will not forget!

Full Speed Ahead

Full Speed Ahead is happy to be providing Neutral Support for all of the NW Epic series. Full Speed Ahead will have a FSA NS mechanic and tent at each check point in case that random root, tree, or suicidal squirrel causes a crash. Seek out the FSA NS mechanic at the check points and they will do their best to get you back in the race.
