Great Britain’s cyclists missed out on their country’s main gold medal chance of day one at the Rio 2016 Olympics but swimmer Adam Peaty set a world record.
Geraint Thomas suffered a late crash in the men’s road race while GB’s three-time Tour de France winner Chris Froome was also down the field as Belgian Greg van Avermaet triumphed.
American shooter Ginny Thrasher, 19, won the first gold of the 31st Games.
Peaty broke his own record in reaching the 100m breaststroke semi-finals.
As the first medals were won, there was drama elsewhere – with a controlled explosion on an unattended bag, while a stray military bullet landed in a media tent.
Big winners on opening day
A gruelling road race ended with Van Avermaet sprinting first across the line after passing Poland’s Rafal Majka in the last few seconds.
British hopes were ended when Thomas crashed on the final descent, after Froome and compatriot Adam Yates failed to stay with the leaders in the 237.5km race.
Welshman Thomas remounted to finish 10th, one place ahead of Froome, who had to be told to register for the race by two BBC journalists – minutes before the start at Fort Copacabana – after failing to hear his name being called over the public address system.
There was a surprise name as the first gold medal winner of the Games – Ginny Thrasher.
A biomedical engineering student, she secured her maiden major international victory in the women’s 10m air rifle, scoring 208.0 to leave China’s 2006 world champion Du Li with silver.
World record for British swimmer Peaty
Adam Peaty – the swimmer who was once frightened of water – scared his rivals with a new world best.
The 21-year-old clocked 57.55 seconds to break his own world record of 57.98 and will bid to seal his place in the final at 03:16 BST on Sunday.
Team GB colleague William Fox-Pitt is more than twice his age, but is eyeing an extraordinary equestrian success.
“I’m lucky to be here,” said the 47-year-old rider, who was in a coma nine months ago after a fall, but leads the eventing competition at the halfway point of the dressage, the first of three disciplines.
Britain scored a notable success in the women’s hockey, beating Australia 2-1 in their opening group match, although the men were beaten 4-1 by Belgium.
Rowers Kath Grainger and Vicky Thornley went through to the semi-finals of the women’s doubles sculls, while the men’s lightweight four and men’s pair also progressed.
Gymnasts Max Whitlock and Louis Smith limbered up for a potential gold medal showdown on the men’s pommel by leading Britain into the final of the men’s team event, but Commonwealth champion Ashley McKenzie was in tears after being knocked out the -60kg category of judo.
Controlled explosion and stray bullet
Brazil’s bomb squad earlier carried out a controlled explosion on an unattended backpack near the cycling road race finish.
The bag may have belonged to a homeless man, a spokeswoman for the public security department said.
A loud blast shook the media seats near the finishing line amid tight security at South America’s first Olympics.
Meanwhile, there was a scare at the Olympic Equestrian Centre – which is located near a military compound – as a bullet pierced the roof of the media tent and landed on the floor. The competition was not disrupted and nobody was hurt.
Rio 2016 organisers have apologised after spectators faced long queues to enter the Olympic Park and said they have increased security staff at checkpoints.
Agony on opening day
French gymnast Samir Ait Said suffered a broken leg while performing in the vault in the men’s qualification event.
Said writhed on the ground in agony while medical officials tended to him and he was carried away on a stretcher to a standing ovation.
Serbian pair Milos Vasic and Nenad Bedik capsized during qualification for the men’s pair rowing semi-final at Lagoa Stadium.
Meanwhile, Brazilians will have to wait a bit longer for their country to earn its first gold medal at their home Olympics after defending champion Sarah Menezes suffered a shock defeat in the judo -48kg quarter-finals.
A day of firsts
- First athlete to represent refugee team – A year since fleeing Syria and being forced to swim for her life, Yusra Mardini, 18, won her women’s 100m butterfly heat, but her time was not quick enough to progress.
- First ever Olympic gold medal for Vietnam – Hoang Xuan Vihn beat hometown favourite Felipe Almeida Wu on the final shot of the men’s 10-metre air pistol competition.
- Games debut for rugby sevens – Great Britain’s women beat Brazil 29-3 and Japan 40-0 in the group stages.
Athletes fail drugs tests
Cypriot weightlifter Antonis Martasidis has joined an unconfirmed Greek competitor as the first two athletes sent home from Rio 2016 for doping.
Russian swimmer Yulia Efimova has been been cleared to compete in Rio after a convoluted drugs case that saw her go through the Court of Arbitration for Sport.
The world champion will line up in the 100m breaststroke heats on Sunday after initially being banned because of a previous doping violation.
Russia claimed their first gold as Beslan Mudranov triumphed in the men’s -60kg judo final.
He is among a team of more than 270 Russian athletes at the Games, about two thirds of the original entry despite the World Anti-Doping Agency (Wada) recommending a blanket ban after a state-sponsored doping scandal.
Long and the short of Rio 2016
Competitors have been getting into the Olympic spirit, taking selfies and sharing photos with athletes from other sports on social media.
