Clare Balding presents coverage of the 157th Boat Race between Oxford and Cambridge from the banks of London's River Thames.

Last year the light blues of Cambridge triumphed by more than a boat's length in front of an enthusiastic crowd of 250,000 spectators. Cambridge lead the annual event by 80 victories to 75.

The race, also a national institution and global attraction, was first contested back in 1829 and stretches four miles and 374 yards between Putney and Mortlake.
