The Houston Half Marathon & 10K course closes at 11 am. Roads will be reopened to traffic in a staged manner after race start based on a 4 hour finish timeline.
Participants will be assigned to corrals to help with race flow at the start of the event. Later corrals will cross the starting some period of time after the official event start, which can impact how much time those individuals have to finish.
Runners/walkers still on the course when roads are about to reopen will be either be picked up and transported to the finish line or offered the opportunity to finish using pedestrian sidewalks along the course rather than the roadways. Please note: this could apply to half marathoners with a pace of over 17 mins/mile or 10k participants with a pace of over 30 mins/mile depending on when they cross the starting line.
