In June he performed well in Italy to qualify in the five-strong New Zealand team at the UCI Para-cycling Road World Championships in Nottwil, Switzerland. He struggled in difficult conditions to perform to his best, which he admits has taken its toll on his confidence.
The head coach of Paralympics New Zealand para-cycling programme and Sharp's former coach, Jono Hailstone, says four men are competing for two spots in Rio.
"Fraser is definitely one of them and it is inspiring what he has been through. It is still pretty much wide open at this stage," Hailstone said.
"What happened in Switzerland would not have got him a spot. We put a lot of emphasis on the timed events like the time trial and track events, because they are so much more controllable. Invercargill is a key event coming up in December."
Sharp is now back home in Tauranga, training as hard as he ever has to be in the best shape possible for Invercargill.
"I am going down to race the time-trial and I want to do an exceptional ride in a good time," he said. "I have a new coach in Ric Reid, who competed at the Commonwealth Games and Olympics. My training is now up to 500km per week and will be going up to 800. I guess it all comes down to my legs now. They told me in Switzerland I am a medal contender so I can still do it."
The biggest hurdle blocking Sharp getting to Rio could be funding. -Donations: www.dreamfunda.com/Member/Fraser
