There are two Meetup teams doing the 9th annual Hub On Wheels event on Sunday, September 22nd. Join my team, called "Greater Boston Meetup 50 Mile," if you would like to do the 50 mile ride. Join the other team ("Greater Boston Bicycle Meetup") if you would like to do the 30 mile route. There is a $45 registration fee, which raises to $50 after September 10th and $55 for day-of registration. SIGNING UP FOR THE MEETUP DOES NOT REGISTER YOU FOR THE RIDE. This is one of the biggest bicycling events in Boston. All of Storrow Drive is closed to motor vehicles, and the entire route is protected and lined with volunteers. The purpose of the event is to promote safe and fun bicycling for everyone on Boston streets.
