The annual ride included 101 pit stops where bicyclists received refreshments, t-shirts and bike tune-ups. Some of the pit stops were scheduled to reopen for the afternoon commute.
Volunteers at the pit stops tallied more than 9,500 visitors during the morning hours, though some could have made multiple stops and some no stops at all. Last year, 8,700 pit stop visitors were reported by SANDAG.
Also part of the event was an afternoon ride along the U.S.-Mexico border.
Among the notable pit stops:
-- SportRx, 5076 Santa Fe St., which along with partners will provide bike tune-ups;
-- the city of Chula Vista will co-host a stop along at E Street and Bay Boulevard with the Living Coast Discovery Center and UTC Aerospace Systems;
-- the city of El Cajon will offer coffee, pastries and other treats from area businesses at their pit stop, 221 E. Main St.;
-- Sharp Memorial Hospital, Outpatient Pavilion, 3075 Health Center Drive, where riders will receive free helmets; and
-- UC San Diego, near the Price Center, which will be one of the largest pit stops.
SANDAG said a ride along the U.S.-Mexico border will commence at 4 p.m. at the San Ysidro trolley station, go to Outlets at the Border, Tijuana River Valley Regional Park and finish at the Casa Familiar at The Front gallery.
