The course.
The SATX 5K starts and finishes at Hemisfair at 8:00 PM on Friday, with one water station between miles 1 and 2 and a one-hour limit. The marathon and half marathon start at 7:15 AM on Sunday and finish at the Finish Line Fiesta in Hemisfair; the course pages give Hemisfair as the start too, though the FAQ still lists the start line as to be announced. Both courses are USATF-certified, and the marathon is a Boston Marathon qualifier. The marathon has 18 water stations, 9 electrolyte stations and 2 gel stations, with a 7-hour limit (16:01 per mile). The half marathon has 8 water stations, 4 electrolyte stations and 1 gel station, with a 4-hour limit (18:19 per mile). Approximate cutoffs sit at mile 6 for both races and at miles 10 and 11 for the marathon, where slower runners are moved to the half marathon or turned back toward the finish. The San Antonio Road Runners lead the official pace teams. Bikes, strollers, skateboards and dogs are not allowed on any course.
