There are opportunities to un next to the water in MdP. Just follow the path next to the ocean. For a nice stop, just tuck into one of the small beach coves and enjoy the ocean. About 1km inland from the water is a wooded area with meandering trails and opportunities to take a mountain bike. There is hunting here in season, so that can be a little off putting. It is a bit deserted, but very charming. Fun running with a friend...
