Upper Otay Lakes Trail Run
In Chula Vista there is a large lake called Otay Lake. It is near the Olympic Training Center and has miles of single track trail to run. The lesser used lake is Upper Otay Lake.
You can access the upper Lake by parking on Otay Lakes Road and running up the paved road until you are above the dam. Follow the fire road around the lake until you cross a small footbridge. Once over the bridge you can fork either left or right. Go to the right along the grassy footpath until you reach a double track trail. Hang a right and follow that down to the lake and loop back the way you came. When you get back to the grassy footpath go right around the ridge then back the way you came for a nice easy 3 mile run.
If you want to do more mileage there is plenty of opportunity at the upper lake. The area is full of single and double track in addition to lots of hills if you want them. You can also hook up the upper and lower lakes for a much longer run. On the lower lake at mile 3.2 when starting from the boat launch there is a concrete drainage tunnel with graffiti all over it. Go through the drainage tunnel. Once through go left up the embankment then right on the paved road. Once at the top follow the fire road around the lake until you cross the footbridge. You can follow the same directions mentioned earlier or explore a new trail.
