Your Local Do-Gooders
We believe that bikes build better communities. That is why we donate a substantial part of our earnings to support community improvement projects that make real differences in people’s lives. We aren’t talking about some nominal percentage, and we don’t ask our participants to go out and fundraise.
By simply signing up and showing up for an amazing day on the bike, you are actively helping Shift Events create a positive impact in the world. Thank you.
