Go in from the Argo trailhead, and turn right. Go down the connector to the "barrel" intersection. Take the hard left and ride Will's. On Will's, take the right at the intersection and ride Swedish. Continue on Will's to the west (spaghetti) intersection. Take another hard left and go up Dave's Maze. When it spits you out at the double track field intersection, go straight across into Family Trail. Ride Family back to the spaghetti intersection. If you're desiring more challenge, take the slight left onto RIM. RIM has a little more climbing and rocks, and will spit you back to the barrel intersection. From there, climb the connector back to the parking lot. That usually makes for a pretty good ride.
If you ride MX, you should be able to handle quite a bit. MX riders tend to transition to mountain bikes pretty well.
Bike racing is good. The people you meet, the struggles you overcome, the highs and lows, the downhills, the finish lines. Bikes in general just make us better people. -Cameron Chambers
