While her limbs remained intact, the same could not be said of Reade's spirit.
"Afterwards I was thinking, 'No I don't want to do it, I don't want to feel the way that I felt through a bike race.'
"I felt depressed. I was down and I didn't want to think about or see the bike again because looking at it made me feel sick."
Quitting the sport
was considered and she suffered another blow when Olympic champion and former mentor Jamie Staff said Reade needed to "
" if she was to avoid "screwing up" in London.
Reade might not have not agreed with all of his comments but she took them on board and significant changes have been made to the rider's programme since the last Games.
There is now a much greater emphasis on the mind.
"The biggest part of winning the Olympics is not about the form and the physical, it's about the mentality," revealed Reade.

"Before [Beijing] I thought the split was 50/50, but I'd probably say 60/40 or even more on my 'mentals' now.
"Everybody who gets to the Olympic final is capable of winning, so it comes down to mental strength and have you got it to perform.
"Having a psychologist and a psychiatrist [Steve Peters] helps me look at things differently and I read a lot."
Reade has sought inspiration from Olympic greats such as
and Dame Kelly Holmes.
"Michael's book was amazing because he didn't just talk about all of the wins, he talked about his lows and how he pick himself up again.
"I can relate to that story because of what's happened to me and it's good just to read that you're not alone in any experience you have in life."
Olympic rival Pajon on Reade
"Riding with Shanaze Reade is amazing because she is the one I grew up wanting to be like. She is a really great athlete and I was proud to race with her at last year's World Championships. I just want to be around her and learn from her."

Reade, who has also won two
track cycling World Championship titles
alongside Victoria Pendleton, and only gave-up her ambitions of competing in
in London due to the increasing competitiveness of riders on the World BMX Tour, says her coach, Grant White, and family were also key to keeping her "in the game".
Raised by her mum and grandparents in a low-income household in Crewe, Reade's mother went to extreme lengths to help her daughter's early career.
"I had won the Europeans in 2000 and I asked my mum if I could go to the Worlds in Argentina and she just couldn't afford it, but she promised I could go to the next one if I put the hours into training.
"I think she was hoping they were going to be in Europe, but they were in America and she was like, 'Oh'.
"She wrote to councils, local businesses and pulled everyone together to fund it.
"When you get older you appreciate it more and I do stuff for the police force and the council who always supported me - you have to give back to people who have helped you out."
"People had come all of that way to see BMX and I wanted to step up and perform for all those who had supported me.
"After what happened [in Beijing] I just wanted to say, 'I'm back and I'm still fighting to win in 2012.'"
"It was a very special moment [standing on the podium] with many friends and family in the crowd, so even if the Olympics don't go a certain way, it'll still be a nice moment to reflect on my career and say I experienced what it was like."
Reade's London 2012 preparations step up a gear at this weekend's
in Birmingham as she bids to retain the
world time-trial title
and reclaim the world super-cross crown she last won in 2010.
And having foreseen she would crash on the final bend in Beijing in a series of recurring nightmares ahead of the last Games, Reade now confesses to dreaming of winning in London later this year.
"An Olympic gold medal would just mean that I'm a complete package.
"I've won British, European and World Championships as a junior and as an elite, but I've never been Olympic champion.
"I still have this internal desire to get it in my home country so that, at the end of my career, I can think I achieved everything there was in the sport."
