Welcome to the Bear Creek Trail Half Marathon/10K/5K -- Winter Edition

UPDATE (1/30/10): Congratulations to the more than 400 runners who came out and ran those EXTREME trail conditions! You all have a lot of guts being out there! Click here for results.

Nice post-race blog report here.

Our summer edition, our most popular event of 2009, took place on August 29, during a much "toastier" time of year. We can almost guarantee you a much, much cooler race during the winter edition!

Whether you are an experienced trail runner or a first-timer ready to get your feet dirty, you should thoroughly enjoy these races. Hikers/walkers are welcome!

If you are looking for a super-fast, flat, easy course to set a personal record, you are probably in the wrong place. These courses have hills. If, however, you are looking for a great time on the trails, with beautiful scenery, awesome support and unique, high-quality shirts and awards, you have come to the right place!

About Briones Regional Park

With its rolling, grassy hills and secluded, shady canyons, Briones is a secret wilderness surrounded by the towns of central Contra Costa County. Although the park is close to Lafayette, Walnut Creek, Pleasant Hill, Concord, and Martinez, there are peaks within it from which you can see only park and watershed lands for miles in every direction.

From Briones Peak, the highest point in the park, there are panoramic views of Mount Diablo and the Diablo Valley to the east, the Sacramento River and Delta to the north, the East Bay hills and Mt. Tamalpais to the west, and Las Trampas Regional Wilderness to the south.
