Twice a year, CSO 5K runners and walkers enjoy a beautiful 3.1 mile USATF certified course on a tree-lined, paved out-and back course through Lake Louisa State Park.

Wildlife abounds including an infamous Tortoise Mound at the half-way marker, and participants are warned that “Wildlife will have the right of way!”

All registered participants receive a T-shirt.  Trophies are awarded to overall male and female winners and each age group top male and female runners will also receive awards.

The next CSO 5K will be held on May 29, 2010 at 7:30am.
