Wallace, a bronze medallist at the 2015 World Junior Championships, sustained a "severe" head injury during the incident on August 17 in Mettmenstetten in Switzerland.

The 22-year-old, who trains full time with the Swiss aerial team, spent a week in hospital after the crash before returning home to complete his rehabilitation.

He suffered no serious injuries apart from serious concussion.

Wallace admitted he has no recollection of the crash, where he hit his head when he fell in the in-run for a big jump.

He was then hauled from the water by team doctors from the Ukraine and Russia.

The University of Bath student has since resumed his training and says he still hopes to represent his country at February's Winter Olympic Games in Pyeongchang.

" was lucky I got over it so quickly - I've got friends who have had smaller head knocks in rugby and have been out for longer," he told BBC Sport.

"Not remembering it meant I wasn't petrified when I got back into it.

"There were butterflies in my stomach when I stood at the top of the jump. 

"But as soon as I did my first flip and got to the bottom, I got a big cheer because everyone knew it was a huge step for me.

"t was a moment of euphoria, realising I could do it and I was fine. 

"It felt great."

Wallace has been using a crowdfunding page to help his ambition of competing for Britain at Pyeongchang 2018 and claimed the crash has made him more hungry to do so.

"As an athlete, when you hear about the Winter Olympics you get that little tingle. I think that tingle has been exaggerated since I've come back from my injury," he said.

"Representing GB and wearing the flag would be an honour. 

"There were a few days when I was scared I wasn't going to be able to make the Games."
