Kick off the paddling season with the 36th Run of the Charles: Boston's premier paddling race.

Run of the Charles, the Charles River Watershed Association's signature annual event, is the largest flat-bottomed boat race in New England and a major event in Greater Boston. The event draws 1,500 racers and thousands more spectators each year!

The Boston Marathon is an annual marathon hosted by several cities in greater Boston and eastern Massachusetts. It is always held on Patriots Day, the third Monday of April.

The Boston Athletic Association (B.A.A.) has organized the Boston Marathon since the event’s inception in 1897. The Boston Marathon is the world's oldest annual marathon and ranks as one of the world's most prestigious road racing events. The event attracts 500,000 spectators each year, making it New England's most widely viewed sporting event.

Mayor Martin J. Walsh and the City of Boston will once again honor Boston's resilience, generosity and strength on April 15, now known as "One Boston Day." The day serves as an opportunity to recognize the good in our community, celebrate one another, and reflect on the spirit and resilience of the people of Boston that was exemplified in response to the loss and tragedies of April 15, 2013.

Individuals and organizations are encouraged to share their plans for One Boston Day on the official website and on social media using the hashtag #OneBostonDay.

"One Boston Day" encourages random acts of kindness and spreading goodwill, and activities across the City will encourage individuals to give back to their community. The tradition came together in 2015 based on the desire expressed by many survivors to pass on the kindness, generosity, and support they received following the 2013 Boston Marathon.

Boston's grand boulevard, Commonwealth Avenue, provides an enduringly popular stroll. The tour parallels the 19th-century filling and development of the Back Bay from its origin at Arlington Street down the seven blocks along the tree-lined, grassy Mall. See how careful effort over 150 years has preserved the "grandness" of the Avenue.

Prior registration is encouraged. Space is limited so make sure you RSVP!
