Colin Turkington and Eugene Donnelly are two of Ulster's most decorated motorsport champions. But their paths rarely cross.
However they will both be in action on Sunday in an end-of-season fling as British Touring Car champion Turkington goes back to his roots to drive a Ford Fiesta and five-times Irish Tarmac rally champion Donnelly takes to the race track.
Both are entered in the six-hour Ford Fiesta endurance race at the Mondello circuit near Naas, an event expected to feature Donnelly's record-equalling Tarmac champion Austin MacHale and former European Ferrari Challenge champion Michael Cullen.
Turkington, who was presented with the overall champion's trophy and the Independents' award at a BTCC ceremony in London at the weekend, will abandon his title-winning BMW to share a little Fiesta with his brothers Gary and James. He is, of course, no stranger to Fiestas having won the UK championship way back in the early days of his career.
It is, however, new territory for Donnelly who is more used to WRC rally cars but he will line up against old rival MacHale who is expected to share a car with his sons Gareth and Aaron. Another Aron, Smith this time, one of Turkington's opponents in the BTCC, is also taking part.
The race starts at 12 noon with each driver scheduled to complete a two-hour stint.
Turkington, meanwhile, has been nominated for the British National Driver of the Year award following his second success in the BTCC series. The presentation takes place on December 7 at the Grosvenor House in London.
