A mellow ramble, 12 to 14 mph average pace, through Concord and Carlisle.
Meet at the Uncle Sam Statue in Arlington Center at 9:30 AM (40 miles) or at the Minuteman Statue in Lexington at 10:00 AM (30 miles). We leave promptly at 9:30 so we can get to Lexington on time. The start is short bike ride from the Alewife T-stop. We will stop in Carlisle for ice cream.
If you are interested, you will need a working bike, spare inner tube, bike helmet, bright clothes, and water.
