The Three Bears is a standard East Bay route. The Berkeley Hills Road Race takes place on this loop. The Three Bears refers to the section on Bear Creek Road which has three climbs called Papa Bear, Mama Bear, and Baby Bear. From Alhambra Valley Road, Mama Bear is first, Baby Bear is in the middle, and Papa Bear is last (at least that’s my interpretation).
Time: 2-2.5 hours
Distance: 35.21 miles
Climbing: 4482 feet
