chino HILL TRAIL series. It lives up to its name. It was very hilly lots of elevation change. We ran on single track for some portions. Beautiful scenery and wildlife throughout. There was good coverage on the aid stations but I go through a crazy amount of water so I needed a camelback recommend that if others know their bodies sweat more than most that they do the same. They had plenty of goodies to munch/drink.
Only complaint is the parking it was $5 and kinda tight at the discovery center.
