“It is still an aim but I've got to work very hard and keep improving to be in for a shout for that”
Shone on her hopes of competing at the 2014 Winter Olympics
But she has astounded friends, team members and medical experts by returning to action in Bath on Tuesday.
"Having come from not even knowing if I could touch my toes or run again, to being able to push a 155kg sled is amazing," said Shone.
"On the first run, I was actually quite nervous. I suppose it was the whole thing hanging over me that if I couldn't do this, then I couldn't ever see myself doing bobsleigh again.
"It's a big step in terms of me logistically being part of the team."
The Weymouth-based bobsleigher fractured her
L1 and L2 vertebrae
in her lower back in the crash that happened in Germany ahead of the 2011 British Championships.
Shone has been working with physiotherapists since the turn of the year and was allowed to start working with weights in June.
"If someone told me Serita would be back pushing a sled on the push track within a year, that would just never have been in the equation," GB Bobsleigh performance director Gary Anderson told BBC Sport.
"I walked into hospital in Germany and the doctors told me that Serita wouldn't walk again. I don't think they realised just how determined Serita is and what she has done is amazing."
