Fast5 Belgrad Forest

Fast5 Belgrad Forest is a night forest run held on the evening of Friday, 9 October 2026 in Istanbul's Belgrad Forest. The start is at 20:30, and the single 6 km course is a dirt forest loop around Neşet Suyu. There are no steep climbs or technical sections; the challenge is the darkness. The route is marked with reflective tape and turning points have lights and marshals, but most of the course is unlit, so a headlamp or torch is mandatory. The field is capped at 600 runners and the event is open to those aged 18 and over. Kits are handed out at the event area on race day between 15:00 and 19:00. The event is organised by Runaway Zone.
