Starts Descanso Gardens, but many join in at So. Pasadena Trader Joes. Ends in Sierra Madre, though everyone of course has to get back to where they started. 40 miles for the short route, add more for the long route to the turn around in San Dimas, not sure how much more since it has been a while. Fast pace, though it will slow a bit during the winter. One of the best local training rides for those who race.
