Course Etiquette:

  • Passing other runners and trail users –if someone is trying to pass you from behind please step off to the side to allow them to pass.  The runner from behind should give a polite warning such as “on your left” and kindly move to the left to let them by. When you are passing another runner, you are required to put on your face covering (covering both nose and mouth).  If you are being passed, please put back on your mask as well.

Riverboat Series - MS & 50K, Half-Marathon, 10K and

Leroy Percy State Park, Mississippi

Dust Bowl Phenomenon

he Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent the aeolian processes caused the phenomenon. The drought came in three waves, 1934, 1936, and 1939–1940, but some regions of the High Plains experienced drought conditions for as many as eight years.

Diablo and San Francisco Bay are visible along the route. There will not be any support or water stations, so we recommend bringing your own hydration. The 10K loop is what we like to call figure 8.
