A redhead with a self-deprecating sense of humour, Lois Pryce is a sort of bike-borne Bridget Jones nearly intrepid despite herself. Why is she undertaking this exhausting 10,000-mile ride through 11 countries &mdash from Tunisia to Cape Town &mdash when she could happily swoon in the arms of Austin, her "wonderful companion and favourite person in the world" And isn&rsquot she woefully unprepared for the African sun, being as she is, white as a "Romanian vampire" While she leaves the first question unanswered, she bravely tackles the second by taking a trip to a sun-bed.
