Cycle to the Source 2019

Cycle to the Source

Our 2019 ride was so much fun! Check back in September 2020 for information about our next ride.

History at Mood St

Who: You! Along with Cambridge Water Department staff and guides from Urban Adventours.  This event is free and open to the public, but for safety reasons is for adults only.

What: Cycle to the Source is a 33 mile bike tour of the Cambridge Watershed. It is a chance to explore where your water comes from, how it is collected, and what steps are taken to ensure the city has clean drinking water. It will include stops at the upper reservoirs, dams, gatehouses, and the CWD field office.

When: TBD - Check back in September 2020 for information about the 8th annual ride.

Where: The ride starts and ends at the Walter J. Sullivan Purification Facility at 250 Fresh Pond Parkway, and explores the Cambridge watershed, which includes the lands and reservoirs in Lincoln, Lexington, Weston, and Waltham.

How: Check back in September 2020 for registration information! All you need is a working bike, helmet, lunch, and water. If you would like to join but need a bike, Urban Adventours rents hybrid and road bikes that are suitable for the event. $65 would cover the cost of the bike, helmet, and delivery to Fresh Pond on the morning of the tour. Visit their website for more information.

Hope to see you at the ride! In the mean time, you can check out pictures or the map from the 2018 ride.
