Sir Chris Hoy has competed in the first event held at the velodrome named in his honour.
Britain's most successful Olympian got on his bike for charity races taking place during the Scottish Track Championships at the Sir Chris Hoy Velodrome in Glasgow.
The 36-year-old cyclist met fans before taking part in the Thunderdrome event, which saw teams compete in a series of cycling races seen at the Olympics. It has been organised by the Braveheart Fund which supports young Scottish cyclists to compete in track, road and mountain bike races. Sir Chris is a patron of the fund.
Before the racing Sir Chris said: "It's amazing to come here and see Scottish cycling flourishing in this incredible facility. I never dreamt we would ever have anything like this. I hope the crowd aren't expecting too much because I've hardly been on a bike for the last 10 weeks, it's been so busy."
Since winning his sixth Olympic gold medal at London 2012 the 36-year-old has said he wants to compete at Glasgow 2014 but will wait to see if he stays injury-free at the top of the sport before making a final decision.
"I couldn't be more motivated to be at the Commonwealth Games in two years' time. When you come in here you can see and imagine just what it will be like. I hope to be there for that and if I can physically do it then I'll be here."
The Scottish Track Championships started on Friday and are being held over three days with 14 titles to be won.
Hoy's former club, the City of Edinburgh Racing Club, has dominated many of the events so far.
Craig Burn, chief executive of Scottish Cycling, said: "Scottish Cycling is committed to developing the sport at every level and we are delighted that we are able to incorporate the Thunderdrome into the weekend and support the Braveheart Fund.
"The facility itself is a superb legacy for Scotland and will aid the development of the next generation of elite Scottish athletes like Sir Chris Hoy himself. We are hoping we might even see the stars of the future begin their winning careers at the first championship event held at the new velodrome."
