21 upcoming half marathons found · 17 with finish-time stats
Tulsa's running life is anchored by the Arkansas River. On any given morning you'll find people moving along the River Parks paths from 11th Street south, some sticking to the smooth asphalt, others peeling off toward the dirt singletrack of Turkey Mountain Urban Wilderness on the west bank. The two worlds - flat riverfront pavement and rugged trail mileage - sit minutes apart inside the same metro.
Fall is when Tulsa runners feel it most: the humidity finally breaks, the city's race calendar stacks up, and downtown streets fill with crowds the way they do nowhere else in the year. If you're training for a half marathon, you're already in the right place and the right season.
By the numbers
The Tulsa races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 15, 2026.
Across the 4 RunSignup half marathon editions with published results on RunSesh, walkers and charity entrants included, the median finisher crossed in 2:18:54. The median winner finished in 1:28:01, and the last finisher typically came in around 3:56:48. Fields have ranged from 334 to 371 runners in the editions that publish that figure, so you won't be alone out there at any pace.
Most races on the calendar also offer a 5K and a 10K, so you can ease into it at the same event with the same crowd and course vibe. If you want to test the distance before committing, several events let you run a 6.55-mile option as a middle step. No race here is half-marathon-only, so there is always a shorter door in.
Fall, running September through November, is the busiest stretch on the calendar, with 6 of the 12 races packed into those months. October alone holds 3. If fall doesn't fit your training block, there are also options in winter and spring, though the calendar is thinner in those seasons.
8 of the 12 races say they give a shirt. The other 4 haven't published giveaway details, which means we don't know - not that they give nothing. If a race shirt matters to you, check the individual race page or reach out to the organizer directly before signing up.
