Triathlon triumph could be family affair

Olympic triathlons are notoriously hard to predict, but two British brothers have become so dominant, the biggest argument is over which one will finish first in London.

Alistair and Jonathan Brownlee, who grew up fell-running and cycling in their hilly home county of Yorkshire, were first and second in last year's world championship. This year, they're at it again.

Younger brother Jonathan, 22, won world triathlon races in San Diego and Madrid, before being beaten into second in Kitzbuehel by Alistair, 24, in June, as the world champion returned successfully from an achilles injury.
