ORONO — The registration deadline is approaching for a seven-day, 400-mile bicycle ride organized by Maine’s largest bicycle advocacy group.

The Bicycle Coalition of Maine’s inaugural BikeMaine ride from Sept. 7-14 starts and ends in Orono and includes overnight stays in Dover-Foxcroft, Belfast, Castine, Bar Harbor and Ellsworth.

The ride is limited to 350 riders and costs $875, which includes meals, beverages and snacks along the route, baggage transport, mechanical and medical support and campsites. So far, about 250 people from 35 states and Canada have signed up.

The registration deadline is Aug. 1.

The ride aims to promote and celebrate cycling while giving participants a chance to explore inland and coastal communities.
