Edinburgh cyclists Evan Oliphant and James McCallum will up their preparations for the 2010 Commonwealth Games by taking to the track in Colombia this weekend.

Both warmed up for the three-day event in South America at the Europa Cup in Barcelona last weekend but failed to make an impression.

Former City of Edinburgh cyclist Craig MacLean will complete the male Scots in action with the Commonwealth Games almost exactly a year away.

But all three will be up against it again in Colombia with former world track champions Hayden Godfrey and Sergio Escobar set to turn out.
