OMV Petrom Bucharest Half Marathon is one of Romania's largest urban running events, held annually in May in the heart of Bucharest. Now in its 15th edition, the event draws over 10,000 amateur and professional runners across multiple race formats: a certified 21km half marathon, a relay race, a 10km run, a 2.5km fun race, and a 1km walkathon. The half marathon holds a World Athletics Label certification, welcoming both elite competitors and passionate recreational runners. The route winds through Bucharest's major boulevards, taking participants past landmarks like the Arc de Triompf and Piața Constituției, making it as much a city celebration as a sporting event.

The 15th edition takes place on 9–10 May 2026, organized by Asociația Clubul Sportiv Bucharest Running Club in partnership with the Romanian Athletics Federation, the Bucharest City Hall, and CTMB.
