The women's C4 and C5 cycling Road Race started on the coast at Pontal.
The race was held over a distance of 84 kilometres, starting with two laps of a flat 15-kilometre
course along the coast, followed by a 42-kilometre section further inland.
Dame Sarah Storey of Great Britain was aiming to win this event for the second time.
She was racing against Anna Harkowska of Poland, who finished second at London 2012.
Eighteen riders started the race.
Two broke away from the rest on the first lap, Marie-Claude Molnar of Canada in blue
and Mari-Liis Juul of Estonia.
Molnar and Juul had a 17-second lead over the rest at the end of the first lap.
Juul slipped back into the chasing group on lap two, Ruan Jianping of China caught and
overtook Molnar.
Ruan had a four-second lead as they headed on to the hill climb section.
Sarah Storey closed that gap and took control of the race.
Storey was the strongest on the elevated section of the course and she won comfortably.
Storey finished almost three-and-a-half minutes ahead of Harkowska.
Crystal Lane of Great Britain finished third.
The men's C4 and C5 Road race was overshadowed by a tragic accident.
Bahman Golbarnezhad of Iran was one of 30 competitors who started.
He was involved in a crash on a mountainous stretch of the
course.
As Golbarnezhad was being taken away by ambulance he suffered a cardiac arrest, and he passed
away soon after arriving at hospital.
The riders were unaware of the serious incident, so the 84-kilometre race continued.
A large leading group turned at the first hairpin, three of them broke away on the second
half of the sea-level lap.
Lauro Cesar Chaman of Brazil, Jiri Jezek of the Czech Republic and Pierpaolo Addesi and
Italy.
They had a lead of 51 seconds as they headed for the undulating part of the course.
Chaman, in blue and green, was the strongest on this steep hill climb.
Adessi was given some help from his coach in an attempt to keep cool.
Jezek was finding it difficult to keep up.
The chasing group eventually caught Chaman and Adessi.
Daniel Abraham Gebru sprinted away.
He was soon caught by Alistair Donohoe of Australia and Yehor Dementyev, who tussled
for first place on the home straight.
The tussle cost both dearly.
Donohoe abandoned his bike, ignored Dementyev and ran over the line, just before Daniel
Abraham Gebru rode through.
The judges disqualified Dementyev and fined him for his involvement in the crash.
Donohoe hadn't crossed the finish line with his bike, so the race was won by Abraham Gebru,
the cyclist who crossed the line on his bike just after the crash.
When Donohoe wheeled his bike over the line almost a minute later, he had slipped to fifth.
The men's B Road Race was shortened by 15 kilometres, so it was run over a distance
of 99 kilometres.
The cyclists rode with a sighted pilot on the front of the bike.
Damien Vereker of Ireland and his pilot Sean Hahessy made a strong start on the flat part
of the course, sprinting away from the field.
Vereker had a lead of one minute and 12 seconds at the end of the first lap.
They continued to ride strongly on the second lap.
A group of 19 stuck together a long way behind, waiting for the mountainous section of the
course.
Vereker struggled on the hill climbs, and he was overtaken by Ignacio Avila Rodriguez
and Steve Bate.
Bate and Avila Rodriguez were caught by Vincent ter Schurre of the Netherlands and his pilot
Timo Fransen.
Ter Schurre and Avila Rodriguez accelerated away from Bate to fight for the gold medal
in the home straight.
Ter Schurre crossed the line first, with Avila Rodriguez second.
Bate finished third, the early leader Damien Vereker did not finish.
The women's B Road Race, was also shortened by 15 kilometres.
There were 17 riders competing, including the London 2012 gold medal winner Robbi Weldon
of Canada and Josefa Benitez Guzman of Spain.
First to make a break was Emma Foy of New Zealand and her sighted pilot Laura Thompson.
They had a comfortable lead at the hairpin.
The lead did not last long.
They were caught by the chasing group.
Iwona Podkoscielna of Poland and her pilot Aleksandra Teclaw were next to make a break,
followed by Foy, Katie Dunleavy of Ireland and London 2012 winner Robbi Weldon.
On the hill climb, Podkoscielna was caught by Dunlevy and her pilot Evelyn McCrystal.
Emma Foy was fighting hard to keep up.
Back on the flat section of the course, Podkoscielna and Teclaw extended their lead again.
Dunlevy and McCrystal could not match that pace.
Foy and Thompson were still in third place.
Podkoscielna and Teclaw finished first, they were almost a minute ahead of Dunleavy and
McCrystal, Foy and Thompson finished third.
