Set in the historic town of İznik, famous for its rich 2,500-year history, the İznik Ultra Marathon presents an exhilarating challenge for serious athletes. This vibrant three-day festival draws over 1,200 participants from around the world, offering an array of trail distances, notably the grueling 160 km ultra-marathon and the challenging 47 km course. The race winds through picturesque landscapes, including 21 villages, fueled by enthusiastic local support that enhances the electric atmosphere. The İznik Ultra Marathon caters to both novice and experienced runners, with shorter distances available for those looking to build their endurance. However, the demanding terrain, especially in the 160 km race that only a fraction of runners complete, makes this event a true test of stamina. Competitors face an ever-changing climate, experiencing all four seasons in just 30 hours, making each finish line a remarkable achievement and a lasting memory.
