The annual spring half marathon and 5k event takes place in downtown Tulsa, showcasing the scenic Arkansas River along the route. Participants receive a tech shirt and a finisher medal, each year uniquely featuring downtown Tulsa’s historic architecture. In past events, medals have included designs of iconic structures such as the Boston Avenue Methodist Church, Philtower Building, and Tulsa Union Depot. The upcoming event will spotlight the 320 South Boston Building, a notable piece of Tulsa’s architectural history. This building, originally constructed in 1917, is renowned for its Beaux-Arts style and once illuminated cupola reflecting weather forecasts. Beer and refreshments conclude the event.
