Paralympic swimming gold medallist Liz Johnson has stepped up her preparations for London 2012 by changing her training base from Swansea to Bath.
The 23-year-old is back in training after recovering from a shoulder injury she carried during her victory in the SB6 100m breastroke in Beijing.
"It's a good feeling to be back. I'm feeling tired, but that means I know I'm working hard," said Johnson.
"London is the big picture now. I moved with a view to defending my title."
She added: "I trained at Swansea for six years and for two Paralympic Games. I've come a long way as a swimmer and become a more rounded person during that time.
"I could have stayed in my comfort zone, but I didn't want to go to 2012 as the same person. I need to evolve as a person and as an athlete, and I think Bath is one of the best places to do that.
"It's a new challenge and the coaching is totally different. It's a great environment and everywhere you look there are decent sportspeople."
