Spring Series 2026
NOTE: 2026 Spring Series will not include the Aramco Houston Half Marathon due to overlap with the Fall Series Houston Marathon race. The 2026 Spring Series races and point allotments will instead commence with the HBA Law Week Fun Run. We encourage those who wish to run the Aramco Half Marathon to do so - it's a fantastic event with a fast course and great support for runners of all abilities.
