About Jeyrun
One club, one family
Jeyrun is an endurance running, trail and mountain club, founded by Salar Piri — one of Iran's leading ultra runners. Our approach: consistent, structured training tailored to each runner, from first-timer to elite.
Every day at 6 AM we meet across different points of Tehran and the surrounding mountains, and every member gets a training plan written for them.
Our values: Friendship · Discipline · Respect · Progress
