Hundreds of people have lined the streets of Birmingham to cheer on participants in two half marathons.
About 200 elite athletes ran in the IAAF Energy World Half Marathon Championships, followed by 12,000 people in the Birmingham Half Marathon.
Some people wore wigs and costumes for the 13-mile run from the city centre to Bournville and back.
Concern was raised over diversions and road closures but the city council said it had tried to minimise disruption.
Final traffic restrictions in the Broad Street area were expected to be lifted by 1800 BST.

The council's Steve Hollingworth said residents' support and patience had been appreciate.
He said: "For an event of this scale it is obviously necessary to close several roads, but we have tried to keep disruption to a minimum."
