Shasta Sands of Time is a muddy obstacle run held at Historic Haws Farms on Deschutes Road in Anderson, California. It begins at 8:00 AM and offers race options for adults and children. The primary choices include a 5K Adult race, a 5K Youth race for participants aged 12 and under, and a 10K Adult race that requires runners to complete the course twice.
The course features mud, water pits, walls, and uneven terrain between obstacles, presenting a messy farm-course challenge distinct from a typical road race. This event attracts families; past participants have included seven- and eight-year-old children, and one runner traveled three and a half hours to attend. Post-race amenities have featured dog tags, vendors, and food trucks. Feedback has also noted practical aspects such as recurring obstacles, challenging walls for shorter runners, debris in some water pits, and uneven ground that can be hard on ankles.
