Fort Ord are my home trails and as stated definitely worth checking out. Once you get to know the trails you can really push the tempo and enjoy the flow. I disagree on one point though… Sand pits are everywhere and the whole place is infested with poison oak.+1 for Fort Ord, tho as noted it's not particularly difficult. Fun can be found, for example trails 50 (north & south), 49, 42 & more. Be sure to get a map cos you're definitely gonna need it, even if you have a gps. It's a great place to explore & "get lost" on the spaghetti network of trails. Sand pits, brake bumps & poison oak are the only negatives, and even those are rare.
