Park Entrance Fee

There is a daily gate fee to enter Cooper Lake State Park of $5/adult and $3/youth – which for our purposes includes anyone competing in the Interscholastic OR Intercollegiate Championships. So even if they’re age 20, if they’re competing in the IC, the $3 fee applies. Children 12 and under are free.

The park accepts cash, check and credit cards. Note that you are required to display the permit on your vehicle windshield when in the park. Groups in buses, please have a head count and payment calculated ahead of time to help prevent a traffic backup at the entrance.


You’ll find souvenirs and a Gatorade or soda pop at the park HQ building, but no food. So load up your backpacks in Sulphur Springs, or stop off at Joe Bob’s convenience store before heading west on Farm Road 71. The Dining page provides some suggestions for local eateries to visit after your run.

All competitors must carry a whistle, wear a watch or other OUSA-permitted time-keeping device and dress appropriately for the weather conditions.

Sulphur Springs, TX, has a warm, humid, temperate climate. March 3-5 is early spring, with historical average high/low temperatures of 62°F/41°F. Light-to-moderate rain or thunderstorms are possible — the chance of snow is less than 3%! Current forecast:
