Thom Evans will compete over 60 metres in the scottishathletics National Senior Indoor Championships at Glasgow's Kelvin Hall on February 19.
The 26-year-old has been exploring athletics since his recovery from the severe neck injury in Wales two years ago which cut short his rugby career.
Evans, who won 10 Scotland caps, is working with coach Margot Wells, the wife of Scottish Olympic gold medallist Allan, and would eventually like to compete in the 2014 Commonwealth Games.
He told the scottishathletics website: "I am looking forward to running in Glasgow. I am excited by the prospect of competing there.
"When I played there for Glasgow Rugby we used to do warm-ups in the Kelvin Hall in the winter so I am familiar with the arena and the track.
"At the moment I am simply gaining some race experience in the 60 metres. It is all new but I am enjoying that and the idea is to build some basic sprinting fitness.
"Further down the line I would think there's more chance I will be looking at 200 metres or 400m. That's more the goal to be honest. You have to start somewhere and get used to actual races as well as training."
Evans sustained a severe neck injury on February 13, 2010 in Scotland's 31-24 defeat to Wales in the Six Nations and was forced to retire in July that year.
Scotland will take on Wales on Sunday in the second round of fixtures in this year's competition.
