Race Overview
The Austin International Half, known as the 3M Half Marathon until 2025, is a point-to-point half marathon that starts on Stonelake Boulevard in north Austin and finishes at 14th and San Jacinto beside the Texas State Capitol. The course follows Shoal Creek south, passes the University of Texas campus and drops more than 300 feet from start to finish. Because the net drop exceeds the World Athletics limit of 1 in 1,000, times are not eligible for records or entry standards. High Five Events organizes the race, which is held on a Sunday in mid to late January.
