More than a million people have applied for tickets for next year's world athletics championships in London – a stark contrast to the empty seats at the recent Rio Olympics.

Athletics greats Usain Bolt and Mo Farah will compete for the final time on the track next summer.

Jamaican Bolt, who completed a triple-triple of 100, 200 and 4x100 metres relay at last month's Games, and Briton Farah, who retained the 5,000 and 10,000 titles in Rio, have both said the 2015 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 recent Games, demand for tickets for London 2017 has been fierce, with applications vastly outnumbering the 700,000 available places.

Organisers said 1,047,000 tickets have been applied for with applications flooding in from 92 countries.

Bolt's swan-song in the 100m final has attracted more than 200,000 ticket applications with the stadium capacity around 50,000 per session.

The event will take place between 4 and 13 August, 2017 and will be held at the Olympic Stadium, which played host to the 2012 Games.

Irish athletes such as 400m hurdler Thomas Barr and 1500m runner Ciara Mageean will be hoping to build on their positive Rio performances in London.

August’s Olympics were poorly attended across the board, with the athletics stadium filling only for Bolt’s major appearances.

This was due to local apathy, the late timing of many big events and the high price of tickets, which put them out of reach of most Brazilians.
