Cycling the MUPs
"Multi-Use Paths (MUPs) pepper the Bay Area and come up in some places you wouldn’t think to look. Here in Contra Costa we have MUPs derived from abandoned rail lines—rails to trails—such as the Iron Horse and the Lafayette-Moraga Regional Trails. Sections of Concord, Walnut Creek, and Pleasant Hill were originally orchards and farmlands, and canals were built to provide water to farmers. Those canals are still there and their service roads have morphed into MUPs. All of them are well used. The orchards are long gone. The Mill Valley-Sausalito Path, which we all use for the Jersey Ride and most excursions out of SF into Marin, is a MUP, built across a tidal mud flat for some reason. The Midpeninsula has a long section of the Bay Trail, much of it mixed terrain, which is a MUP. In fact most of the Bay Trail around the Bay is or is conceived as multi-use. The Bay Trail in Berkeley/Emeryville is part of that network. The Los Gatos Creek Trail, which we use in the SF-to-SJ ride is also a MUP. Further south we have the Monterey Bay Trail that starts in Castroville and goes to Cannery Row.
In the past I avoided cycling on MUPs. The main reason was safety. At that time I thought it was safer to ride amidst cars than with joggers, doggers, and wayward toddlers. I also was rarely going less than 15 MPH, which is the standard speed limit on MUPs. Nowadays I ride on them frequently and enjoy them immensely. As car traffic has increased and become more wanton, the roads are less welcoming and the experience anything but calming and peaceful whereas the MUPs can provide tranquil relief from motordom. We may not realize it but riding with traffic consumes mental and emotional energy. There is much to attend to in order to stay safe and that is anything but conducive to relaxation and recreation. I’m not a fan of recreational cortisol."
