A bike ride for social change!
29th Annual
June 19th
(Originally scheduled for June 5th, now using rain date)

The Bike-A-Thon is Bikes Not Bombs' largest and most exciting event of the year! Each rider registers and then fundraises at least $150 (and $75 for youth) to support Bikes Not Bombs' Youth Programs and International Programs. Then on June 19th (reschedule due to rain from June 5th), hundreds of cyclists join together on a ride for social justice along one of our scenic routes through greater Boston. Bike-A-Thon riders are ambassadors of BNB's mission to promote environmental sustainability and social justice, and all fundraising goes directly to making Bikes Not Bombs' programs possible!

Get your friends! Form a team! Many people find the Bike-A-Thon more fun and memorable when participating with a group of their favorite folks. Teams often create costumes for the Bike-A-Thon and can even fundraise together if all team members register at the same time. Plus, teams are eligible to win cool prizes! We have prizes for the team that raises the most money, has the most new riders, and the best costumes. To form a team, simply specify a team name during the registration process.

Fun & easy fundraising!

Fundraising challenge clubs and prizes

Our two special fundraising clubs recognize individuals who are extremely successful in spreading the word about Bikes Not Bombs and collecting donations! Riders will be automatically enrolled in each club once they surpass the club's minimum fundraising level. You can be part of a club and a riding team at the same time, so don’t hold back!

  • 5 FREE raffle tickets
  • Temporary tattoos featuring the Hubs & Kisses logo

  • $50 gift certificate to BNB shop (and $100 if you raise over $1000)

We make it easy to raise $150 with our online fundraising system! You make your own page, email it out to friends and family, and then watch the money roll in. We also have lower fundraising requirements for young people (just $75 for ages 3-17, and no fundraising required for ages 2 and under). Many people bring in way more than the minimum; and so for those of you that go above and beyond, we show our appreciation by giving you all sorts of awesome prizes! In addition to our challenge clubs' perks, the top three fundraisers will receive something special!

Four routes!

Our route system. Click map to view fullscreen.

Choose between 10 miles, 30 miles, 50 miles, or 80 miles. Then ride in solidarity with all riders returning on the same path for the rider after-party! The route system is essentially one 80 mile loop, going west-southwest, with conveniently placed shortcuts designed to suit all riding levels. Each route has at least one rest stop with abundant food and water, and the distance between stops never exceeds 18 miles. Routes will be clearly marked but we also provide back-up paper maps and a digital smart-phone map. GPX routes will be available a few weeks before the event. And as always, these roads will offer some of the most amazing cycling you'll find anywhere in Eastern Mass!

All rides start and end in the SW Corridor park in front of the Stony Brook T Stop, near the corner of Boylston and Lamartine St. Routes are subject to change and final GPX data will be available in June.

Read on for more info about each route...

10 mile ride

This route is perfect for the whole family, with many wide, safe, low-traffic roads that put any rider at ease. The rest stop has a playground and while the route is not entirely free of the inevitable uphill, the way back is almost entirely flat or downhill. Some urban riding skills are required.

30 mile ride

Thirty miles is perfect for cyclists who do not want to do much training but want to push themselves. All of the uphill sections on this route are relatively short and the roads are smooth, many of them have been recently resurfaced! Half way through the journey, you'll find a rest stop at the lovely Powisset Farm with plenty of food and water.

50 mile ride

After the first rest stop in Medfield, the return trip is where the 50 mile route really shines. This route creatively weaves together the best roads and sites from the Dover area to form a secluded and adventurous ride with two rest stops. Aside from a handful of short stretches on main connecting streets, you'll find yourself forgetting cars even exist!

80 mile ride

Our longest Bike-A-Thon route ever clocks in just over 80 miles! Your grin will be infectious as you enjoy the smooth, beautiful, and traffic-free roads out near Millis and Holliston. And if the scenery's not enough, you'll even have the option to swim in a pond at the second rest stop! In order to finish in time for a late lunch at the after-party, riders should be able to maintain at least 11 mph average speed, with 20 minute breaks at each stop. Note that a stretch of this route will be unmarked, check out this supplementary map.
