Rio 2016 day two: Adam Peaty wins gold as Jazz Carlin claims silver in the pool

Adam Peaty and Jazz Carlin broke Team GB's medal duck at the Rio 2016 Olympic Games in a stunning night in the pool on day two. Peaty won the men's 100m breaststroke in a world record time of 57.13 seconds while Carlin claimed silver behind Katie Ledecky in the first medals won by Great Britain in Brazil.

Peaty becomes the first individual Olympic champion from Britain since 1988, when Adrian Moorhouse won the same event at the Seoul Games. Carlin meanwhile bounces back four years on from failing to qualify for London 2012.

James Guy could add to the medal-rush on day three after he qualified for the men's 200m freestyle. The reigning world champion will start as the eighth fastest qualifier but will be in the shake up for the medals alongside the controversial Chinese swimmer Son Yang.

Michael Phelps meanwhile claimed a record 19th Olympic title after staring for Team USA in the men's 4x100m relay. Phelps came out of retirement to compete in Rio and produced a virtuoso display on the second leg to inspire a surprise victory ahead of the teams from France and Australia.

Earlier, fencer Richard Kruse missed out on becoming Britain's first medallist of the Games after he finished fourth in the individual men's foil. The Londoner was defeated 15-13 by Russia's Timur Safin in the bronze medal match, after earlier being denied at least silver by American Alexander Massialas.

Lizzie Armitstead failed to rouse herself following a reprieve having missing three drugs tests in the last 12 months, after finishing fifth in a chaotic women's road race, as the course claimed further victims. The men's event had seen several crashes on the final descent and a similar fate befell their female counterparts in the Brazilian capital.

Netherlands' Annemiek van Vleuten led heading into the closing stages but fell heavily after being thrown from her bike. The 33-year-old has been taken to intense care where she has been diagnosed with three cracks in her spine.

Fellow-Dutchwomen Anna van der Breggen went on to win the race after her group including Emma Johansson and Elisa Longo Borghini caught American Mara Abbott - who had initially benefitted from Van Vleuten's miss-fortune. Armitstead was next over the line but she never troubled the podium as she struggled on the gruelling course.

The first diving competition also saw Britain miss out on a medal as Alicia Blagg and Rebecca Gallantree surrendered a medal position after two dives, to finish a credible fifth. Gold went to China, as Wu Minxia won a record fifth diving Olympic title.

Great Britain women's sevens will guarentee themselves a medal if they overcome New Zealand in the semi-final on day three, after overcoming Canada and Fiji in Rio. In the sport's debut in the Olympics, the medals will be decided on Monday [8 August], with Australia and Canada making up the other last four clash.

Andy Murray and Johanna Konta joined Kyle Edmund and Heather Watson in reaching the second round of their respective singles competitions. The defending champion Murray overcame Viktor Troicki while 10th seed Konta knocked out Stephanie Vogt in straight sets. Elsewhere in the singles competition, a repeat of the bronze medal match four years ago saw a similar result as Juan Martin del Potro shocked world number one Novak Djokovic in two sets.

Murray was however unable to repeat his success in the men's doubles, alongside brother Jamie Murray, as the number two seeds were ousted by Brazil's Andre Sa and Thomaz Bellucci. Serena and Venus Williams, champions in 2000, 2008 and 2012, meanwhile lost for the first time in the women's doubles to Barbora Strycova and Lucie Safarova of the Czech Republic.

Joshua Buatsi continued Britain's 100% record in the boxing competition after stopping Kennedy Katende in the men's light heavy 81kg class. The Ghana-born boxer takes on former world championships silver medallist Elshod Rasulov of Uzbekistan in the next round.

Hotly tipped British pair Heather Stanning and Helen Glover were forced to wait to begin the defence of their women's pairs Olympic title after high winds forced the rowing schedule to be postponed. Treacherous conditions had overshadowed the opening day at the Lagoa Stadium - with the team from Serbia capsizing on the first day - but officials ruled that no racing could take place just 24 hours later with all events pushed back.

GB women joined their male counterparts in reaching the team gymnastic final - but not without a scare. Ellie Downie, 17, landed on her neck during her floor routine and received medical attention before resuming the competition. The team including four-time Commonwealth champion Claudia Fragapane qualified fourth for the final behind United States, China and Russia.

Colin Oates was unable to turnaround Britain's plight in the judo competition after losing to France's Kilian Le Blouch in cruel circumstances in the -66kg class. Neither Judoka could register a point in the designated five minutes, with Oates eventually crashing out by committing a third shido in the sudden-death overtime.
