Arrived in stadium just as the pole vaulter's pole snapped, so was a bit too discombobulated to really notice.
What was really nice was that the loudest cheering of the session was for Sarah Attar, the first woman from Saudi to compete, as she completed the women's 800m for 30 seconds after everyone else had finished.
Very sorry for Daniel Awde though - he won the 100m which was his first decathlon event, with a personal best, then got hurt, did two disallowed long jumps but finally an OK one, but then had to pull out of the whole thing.
