Once again marathon fever grips the capital, as more than 25,000 athletes make the now classic journey from Greenwich Park to
Westminster Bridge.
The men's entry for the ADT London Marathon is the most impressive yet. It includes the world champion
Douglas Wakiihuri of Kenya, the runner-up in Rome,
Ahmed Salah of Djibouti, and Rob de Castella, twice the Commonwealth champion. Favourite for the women's race is Aurora Cunha of Portugal.
But as well as the serious athletes running for prize money of over E250,000, today is. about the fun runners - the men and women who will be pleased merely to complete the 26-mile (and 385-yard) course and raise thousands of pounds for charity.
Live coverage of the whole race, with commentary by RON PICKERING and BRENDAN FOSTER Technical co-ordination

The elite athletes are already across Westminster Bridge and relaxing. Still out on the course, however, thousands of men and women are winning their own private battle with weariness. They are determined to finish. Additional reporting by LUCY PILKINGTON and STUART STOREY

Pigs have everything going for them except good PR.
They are branded fat, greedy and rude, but in reality they are gregarious and, well.... cute. Why else would people have erected mock-Grecian temples in their honour, buried them in gold caskets and immortalised them in verse?
Chris Baines sets out to explore the curious relationship between people and pigs with the help of a film-star pig, a woman whose house is a swine shrine and a pigsty fit for a god.
Also, a day in the life of Herefordshire vet, Francis Anthony.

Tibet: the Lost Nation
This year in Tibet, new riots against Chinese rule led to many deaths and the imposition of martial law.
Tourists were expelled, but brought back eyewitness accounts and dramatic new pictures. Tibetan refugees in India also tell their tragic stories of life in Tibet, 30 years after the great Tibetan uprising against the Chinese. Exiled in India, the former God-king ruler of Tibet, the Dalai Lama, and 100,000 followers have rebuilt their monasteries and kept alive their ancient religion. Their government-in-exile patiently awaits a recall to Tibet. But will it ever come?
Tibet, for all the power of its religion and nationalism, may already be the latest in a long line of small nations swallowed up by powerful neighbours.
