Stay in shape and get a little muddy this winter as we head for the rolling hills and single track trails in San Mateo County. Join us for a fun run/hike/walk at Huddart Park in beautiful Woodside, CA. If single track, tree covered trails with hills and some banana slugs are your idea of a fun Saturday morning.... the Mermaid Trail Run WILL put a smile on your face.

T9 Mermaid Run Woodside routes

Some of the hills you can run, some you'll hike and some you'll just be thinking what goes up must go down. We do think you will enjoy the beauty this course has to offer.

The Mermaid Trail run is a great way to keep yourself motivated and active during the winter months. In the spirit of trail running and enjoying the beauty of the outdoors, the run is centered around fun and spending time with fellow Mermaids out on the trail. Our third year at Huddart Park, this run boasts of serene and peaceful trails, heavy canopy, oak trees, lichen, banana slugs, deer, steep hills and a finish line party to celebrate your run. Hiking and walking are perfectly acceptable. We want you to find your happy pace.


The Mermaid Dash is a great way to introduce girls to trail running. The fun run/walk/hike allows girls to participate and experience the joy of crossing the finish line in a safe and supportive environment. Mermaid Dashers receive a medal and post race food.

Parents are encouraged to let Mermaid Dashers run/hike on their own, however a parent or guardian is welcome to run alongside young or shy Mermaid Dashers.
