Definition of an Advanced Rider:  People in this group are strong and fearless bicyclists or enthused and confident
   bicyclists.  These are people who will ride regardless of road and weather conditions, or are comfortable in riding on a
   road even if it does not have a bike lane.  (This group of people uses riding for commuting, enjoys a faster speed, and 
   likes to go faster on streets compared to the Recreational Rider)

Definition of a Recreational Rider:  People who enjoy bicycling when they are confident in their safety, or people who
  would enjoy bicycling if they felt safer doing it.  (This group of people like the group setting, like mostly trails and some 
  bike lanes, and move slower then the Advanced Riders.)
