Sir Chris Hoy has helped launch the official ticketing guide for the 2014 Commonwealth Games, as the one year countdown to the sporting event begins.
One million tickets will go on sale on August 19.
As an ambassador for the Commonwealth Games in Glasgow, Sir Chris Hoy will today kick-start the one year to go countdown.
Speaking to Daybreak about his role, he said it was a "very exciting time" and he is "proud" to be involved.
Sir Chris also described his visit to the velodrome named in his honour as "surreal".
The One Year to Go milestone is being marked with a series of images capturing a giant number one figure positioned at some of Scotland's best known spots.
With 365 days to go, almost all the sporting venues are already completed and open to the public, and Glasgow city officials say they are pleased with the pace of progress.
History has already been made in Glasgow with the largest peacetime recruitment and regeneration project in Scotland.
The construction of world-class sporting venues, new infrastructure and a multimillion-pound economic boost are some of the benefits that have come the city's way.
Sir Chris Hoy will kick-start Glasgow's countdown to the Commonwealth Games, the largest multi-sport event ever hosted in Scotland.
The opening ceremony takes place at Celtic Park on July 23 next year, when athletes from across the Commonwealth will officially begin their 11-day quest for medals.
Around 15,000 people followed in the footsteps of medal-winning stars today when they took part in a race at the Olympic Stadium, crossing the finish line.
Olympic gold medallist Sir Chris Hoy joked that he had not taken part in today's National Lottery run at the Olympic Stadium because he is "better on wheels than on foot".
Sir Chris said the run was a chance to "thank the British public".
