Former world indoor champion Dwain Chambers is set to race in the 60m at the UK Indoor Championships at the age of 45.
Chambers qualified for February's event by running 6.81 seconds at a meet in Lee Valley earlier this year. He was banned for doping in 2004 but returned to the sport in 2006 and won the 60m world indoor title in 2010.
The qualifying time for the World Indoor Championships, which take place in Glasgow in March, is 6.58secs. Chambers, who last ran for Great Britain in 2014, attempted to break into American football twice - during his two-year doping ban and again in 2007 - before an unsuccessful trial spell at rugby league club Castleford Tigers in 2008.
Dwain took gold at the World Indoors in Doha in 2010 and bronze two years later in Istanbul. He officially retired in July 2017 but also ran in the British Indoors 60m Championships in 2019 only to be disqualified for a false start in semi-finals.
