2027 San Marcos Half Marathon 10k and 5k

The San Marcos Half Marathon, 10k, and 5k offer runners three distance options in San Marcos. The half marathon is noted as one of the more challenging routes. Its course combines difficult hills with flatter sections, making it more than just a straightforward road race from beginning to end. The half marathon follows Texas's oldest half marathon course, providing the event with a degree of historical distinction. All finishers, regardless of distance, will receive a medal. Awards are presented to the top four finishers in each race category. Age-group results are determined by chip time, as participants begin in waves.
