You can do this solo or with a team of up to 3 people.  You'll get a scavenger hunt sheet at the meetup; there's numerous stops where we have activities scheduled (we've previously had bike kickball, a bike rodeo, racing on kid's bikes, lots of great fun!).  Points are awarded for winning events as well as collecting scavenger hunt answers along the way.  This isn't a race; we all need to be at the meetup points at the same time.
