Calero has everything you would expect from a trail run in Santa Clara. The 9k is run on a fire road while the other distances are split about 60% fire road, 40% single track. Most of the run is on the exposed grassland hills though there are still miles of California Oak woodlands. There are beautiful views of the valley from Bald Peaks Trail. This is a hilly course and may be one of the toughest you’ve ever run.
