30 Days of Biking (a.k.a., 30DOB) is a pledge to ride your bike every day in April — any distance, any destination, in any kind of weather — and share your experiences online with the hashtag #30daysofbiking. There’s no minimum distance. If you miss a day, no worries. Just keep riding and don’t give up!
Founded in 2010 with 300 participants, in Minneapolis, Minn., 30DOB today boasts more than 8,000 pledged riders in dozens of cities around the world. And best of all, it’s free to everyone everywhere.
