More than a million people have applied for tickets for next year's world athletics championships in London where greats Usain Bolt and Mo Farah will compete for the final time on the track.
Jamaican Bolt, who completed a triple-triple of the 100m, 200m and 4x100m relay at the Rio Olympics, and Briton Farah, who retained his 5000 and 10,000 titles in Brazil, have both said next year's championships will be their last.
Bolt plans to hang up his spikes after the event while Farah intends to switch his focus from the track to the marathon.
Unlike in Rio, where empty seats were a depressing feature of the Games, demand for tickets for London 2017 has been fierce, with applications vastly outnumbering the 700,000 available places.
Organisers said 1,047,000 applications had already been made from track and field fans in 92 countries.
Bolt's swan song in the 100m final at London's 2012 Olympic stadium has attracted more than 200,000 ticket applications with the stadium capacity around 50,000 per session.
