Course Map: Chosen Half Marathon

While the full marathon follows an out-and-back course that starts and finishes along the Guadalupe River in the historic town of Gruene, the half marathon starts at the mid-way point of the 26.2-mile race, along River Road. From there, runners in both races follow the route as it winds along the river all the way to Edwards Boulevard, where they turn left and head into town, all the way to Ervenberg Avenue, where you’ll turn right and then turn again on Gruene Road before crossing the finish line.
