Lake Del Valle Run, Livermore, CA 12 Saturday Nov 2016 Posted by tvrclub in Group run, trivalley running club ≈ Leave a comment Tagstrivalley running club On November 12, 2016, we didn’t have our group run. Instead, some of our members ran own their own from Lake Del Valle Staging Area to Lake Del Valle Regional Park and back. Great weather and run! Photo credited: Sandra V.
