Fremont, United States of America
12 mile long bike trail follows the Alameda Creek flood-control channel from the hills to the bay. The paved trail is entirely car-free thanks to underpasses beneath each cross-street. About two miles from the bay, you can optionally go to Coyote Hills for a good view. From there, you can proceed so
uth to the Don Edwards Wildlife refuge, and then west to the bike lane over the Dumbarton Bridge. Starting from the easternmost point on the trail (at the Niles Staging Area on Old Canyon Road) means that you will generally go downwind last when you are most tired.
