ELEVEN Večerní běh is a 5 km night run in Jablonec nad Nisou, starting at 8:00 PM from the Volt Brewery complex. The race is also known as the “Pětka,” the Czech shorthand for a five-kilometre run, and its tagline frames it as a run for joy in an early-evening rhythm.
The course goes around the Jablonec dams, then into forest sections beyond them, mixing asphalt with forest paths on gently rolling ground. All participants start together, with categories for boys and girls up to 15 and for men and women aged 16 and over. This event marks its 10th anniversary, and the finish-day extras include material prizes for category winners and a large tombola.
