Bike the Arb

Man and woman on bikes high-fiving

Join us for our third annual Bike the Arb event! The day will kick off with a 19.7K bike race, looping cyclists around Three-Mile Drive and out to the Farm at the Arb for three laps. Racers will enjoy the rolling terrain peppered with interesting flora and fauna as the route winds them through the Arboretum’s unique plant collections and specialty gardens. 

Bikers of all ages and abilities will be challenged and thrilled by this beautiful course. Racers can go for their best time, or simply enjoy a unique bike experience at the Arboretum. Prizes will be awarded to top finishers.
