Britain's Edwards is planning to jump again at Bavaria's Garmisch-Partenkirchen on January 1st, a World Cup large hill event, and is set to come to Germany to train next week.
He came last in the 70m (229ft) and 90m (295ft) ski jumps at the 1988 Calgary Winter Games, but earned plenty of media attention and became an unlikely hero of the Calgary Games.
The married father of two is planning to fly to Germany next week to prepare for the event.
"I'm still fit and in pretty good shape and I wanted to do it before it was too late for me physically," Edwards told the Gloucester Echo newspaper.
"This will be my last chance to have a go and see if I can still do it,” he said, adding that "I've always had that 'have a go' spirit.
"It's not reckless because I think about the risk and every conceivable thing that could go wrong. I am nervous but also quite excited."
Edwards has lived a colourful life since Calgary. He studied for a law degree, and has also worked as a motivational speaker, won a celebrity diving competition on British television and was a torch-bearer at the 2010 Vancouver Winter Olympics.
Now he is hoping to roll back the years having had eye surgery and no longer needs his trademark thick glasses – which could also be a disadvantage.
"It is giving me the opportunity to go off a 125m (410ft) ski jump for the first time in almost 18 years," he told the BBC.
"Because I have had eye surgery, I can see where I am going now, so that might cause problems because I might not want to go down the jump."
