Short, steep, hard-buffed trail in most months. Will wake up the calves for sure. Can be extremely slick post rain. Watch for mountain bikers coming down the trail.
From the treeline, pick the steep switchback that goes up and to the right into the trees in between Marshall Road to the A-Frame and Rumbling Paddoka. This is my favorite warm up trail. The trail rises steep, levels out then rises quickly again between the trees to the A-Frame or East Tower for a great view of the whole Lagoon from the east and beautiful Vaca Valley.
