Registration has opened for the I Bike Sonoma County Century, the inaugural benefit ride that is being staged by the Sonoma County Bicycle Coalition on June 22.

The ride, which is being limited to 1,000 participants, has routes of 17, 35, 66 and 103 miles, starting and finishing at the Whole Foods Market at Coddingtown in Santa Rosa.

It is the first ride being staged by the coalition, a non-profit organization that is an advocacy group for cycling in Sonoma County, provides bike parking at events and puts on an annual bicycle expo.

Sponsors include whole Foods Market, J&D Services, Codding Enterprises, Coddingtown Mall, Elevengear, GHD, Kaiser Permanente, REI, ShiKai and Sutter Health.

Priority registration opened Thursday for coalition members and for riders who pledge to raise $250. Regular registration opens Monday.

The fee is from $15 to $110, but the fee is waived for riders who pledge to raise $500.

Registration, routes and information on the ride is at the coalition's website,
