Full schedule available on BBC Sport website

Cavendish, from the Isle of Man, has said he hopes to "light the fire" for the GB team over 250km of tarmac, finishing on The Mall.

The 27-year-old won last year's Olympic test event, over a shorter version of the course, and is the reigning world champion.

  • SWIMMING (11:17-11:49): Hannah Miley, women's 400m individual medley

Scotland's Miley, 22, is Britain's other big medal hope on day one. She enters this event as the world silver medallist and is ranked third-fastest in the world this year, behind Elizabeth Beisel of the United States and China's Zheng Rong Rong. Michael Phelps and Ryan Lochte will also be in action.

  • SHOOTING (08:15-09:30 qualification, 11:00-11:20 final): First gold medal of the Games

While Cavendish has been labelled the likely candidate for GB's first gold medal, the first title to be awarded at London 2012 will be the women's 10m air rifle. Jen McIntosh is Britain's entrant, ranked 52nd in the world, with China the favourites to win.

  • ARCHERY (09:00-18:26): Chance for GB men's team medal

Britain's male archers have had an impressive few months in the run-up to London 2012, led by Larry Godfrey. The 36-year-old will be part of a three-man GB entry for the men's team event at Lord's.

  • ROWING (09:30-09:50): First heats at Eton Dorney

Watch out for Heather Stanning and Helen Glover in the GB women's pair, who will be among the first to race as the Olympic rowing events begin in Berkshire.
