Runners follow an out-and-back course at Houston’s RunGirl Half Marathon, which starts in Alexander Deussen Park and runs back and forth between there and Eisenhower Park, which lies adjacent to it here on the southern edge of Lake Houston just to the northeast of the city’s downtown. From there, runners then head east into Eisenhower Park for a loop along Walton Road before returning to Aqueduct Road and then heading back over into Duessen Park.
