It depends. Mountain biking is different than triathlon where USAT rules dictate that you stay on the right and pass on the left. For mountain biking, it will depend on the rules of the race director and what organization is governing the race.

Our XC race series are governed my Norba. We also have additional rules as per the director of the WI state series. For our series you are supposed to ask for a pass, then the rider in front of you should move either left or right (depends on terrain and situation). It's all about safe passing and communication. If there isn't room to pass, then you have to wait until it's "safe".
