NWMTB Series was born from dedicated riders and racers committed to brining quality Cross Country racing back to the Pacific North West. At home on the tacky dirt and root filled trails of the NW, we’re authentic off road nuts with decades of racing under our belts. Racing bikes is a part of our pedigree. Let us share with you our passion for great single track. Let us show you a good time. Wed Night Worlds continues to follow 20 years of history and tradition. We’ve resurrected a classic Seattle area race series at N Sea Tac Park. Over the years and hundreds of man hours spent, we’ve reclaimed some of the best inner city XC trails available. Come play with us!
