The 16th freshnlo Pedal for Scotland will take place in September, with rides to suit all abilities.
Mark, an ambassador for the event, will take part in the 47-mile Challenge ride between Glasgow and Edinburgh.
There are also shorter family rides in Edinburgh and Glasgow, and a timed 110-mile Sportive route between the two cities for more experienced riders.
He said: "This will be my fourth time taking part in the freshnlo Pedal for Scotland 47-mile Challenge ride.
"Every year I am struck by the huge variety of ages and abilities who come together to take on this brilliant route, from beg-inners and people returning to cycling to those who use their bikes on a daily basis.
"There is such a great atmosphere on the day and I can't wait to line up for the 2014 event."
