The Iowa Renewable Fuels Association has been promoting clean fuels this week during the 2025 Register’s Annual Great Bicycle Ride Across Iowa (RAGBRAI) by encouraging all support vehicles to fuel up with E15 or B20. IRFA has also provided “Riding to a Greener Future” jerseys to members of the renewable fuels community riding during the weeklong event. 

“RAGBRAI is a celebration of Iowa’s communities, landscapes, and people- including our farmers,” said IRFA Marketing Director Lisa Coffelt. “By choosing E15 or B20, support drivers can help power the ride with homegrown fuels that support Iowa agriculture, improve air quality for riders, and save money at the pump. Anyone with questions about renewable fuels should just ask the riders wearing IRFA jerseys.” 

In its 52nd year, RAGBRAI is the oldest, largest and longest recreational bicycle touring event in the world, held this year July 19-26.
