Fern and Sarah bite back.

Fern and Sarah are cycling from John O Groats to Lands End, along with support driver Tristan, raising money for Macmillan Cancer Support.

Yesterdays journey took them from the village of Carsphairn to here in Gretna Green.

The highlight of the journey so far has been to conquer a large hill near Inverary, spurred on by Ferns optimism.

The lowpoint has been the discovery of midges (A small fly, common in Scotland, with a taste for human blood).
