As the sun sets over the Qatari capital's mishmash of skyscrapers, the parkour enthusiasts hurl themselves off walls and walkways, surrounded by palm trees as they listen to hip-hop.
The word parkour derives from parcours du combattant (obstacle course), the classic obstacle course method of military training proposed by Georges Hébert.
Parkour, an extreme sport also known as free-running that originated in France in the 1990s, involves getting around urban obstacles with a fast-paced mix of jumping, vaulting, running and rolling.
Parkour has thousands of loyal followers and practitioners around the world, but it remains rare in Qatar.
Conservative attitudes towards exercising in public in the Gulf country mean practising the sport can be tricky.
