Ambassador Network

Ambassador Network

Climate Ride Ambassadors are more than just participants; they are leading the charge towards a more sustainable future while helping Climate Ride shift into higher gear. Meet our Ambassadors below!

Climate Ride's Ambassador Network inspires future riders and creates outreach opportunities for various local groups and supporters.

Drawing on their personal experiences of participating in Climate Ride events, ambassadors motivate others who are curious to learn more about Climate Ride and share what to expect from fundraising, preparing for the ride, and how participating can be a life-changing and valuable experience. By sharing their extraordinary stories they help to engage people around the Climate Ride mission and expand the network of individuals and organizations who are a part of our community. 

Ambassadors of the Climate Ride Ambassador Network are previous participants and leaders who have shown a commitment to the Climate Ride mission in their personal and professional lives. They embody the culture of Climate Ride and work towards a more sustainable future, a stable climate, and better bicycling infrastructure.  Among our Ambassadors are sustainability leaders, innovative green architects, cross country cyclists, climate champions, and all around rockstars that help Climate Ride shift into a higher gear.
