The 31-year-old was crowned Commonwealth champion in July and threw a personal best and continental record of 62.34m to win the European title in Swansea last month.
He wrapped up his season with victory at the IPC Grand Prix Final in Birmingham, his throw of 60.01m almost ten metres longer than that of main rival Jeremy Campbell who finished second.
I want to be throwing close to 65m in Rio so we’re bang on target now
And Greaves believes his preparations for Rio 2016 are right on track as he looks to reclaim the title he won at Athens 2004 – with next year’s World Championships all important.
“To become world champion next year would be the icing on a great couple of years,” said Greaves, speaking at National Paralympic Day.
“It’s quite a long year so we will hit a bit of form maybe May or June time and then dip into some more training right through until November.
“Hopefully [the Grand Prix win] sent out a message to Jeremy that it won’t be all his own way next year at the World Championships. We’ve had rivalries ever since he beat me at Beijing 2008 and it’s great to have that.
“It pushes me on, it pushes him on and it’s great for Paralympic sport because the public get to see big throws. It’s a long way and I think they can relate to that because it’s not far off able bodied standard.
“It’s been a great summer for me. It’s taken a lot out of the body but it’s so pleasing to come away with a personal best of 62.34m, which is just incredible and all the hard work has been well worth it.
“I want to be throwing close to 65m in Rio so we’re bang on target now. We’re only a couple of metres away so if we can add a metre or so in a year then we will be right up there. A 64m or 65m throw would hopefully be enough for the gold medal.”
Greaves revealed retirement plans have been on his mind but with the 2017 World Championships taking place in London, he believes there would be no better setting to bow out than the Queen Elizabeth Olympic Park.
“I’ve thought about retiring but I’m going to wait because I really want to go out with a bang in front of a home crowd,” he added.
“I loved the experience in London two years ago so I’m going to hold out until 2017 and hopefully go and put on a show for the British public and go out with a bit of a bang in my home country.”
