Repsol Honda's Casey Stoner will officially retire this weekend in Spain.

Repsol Honda Team’s Casey Stoner admits he has a case of mixed feelings entering this weekend’s final round of the 2012 MotoGP World Championship, on the eve of the final race in his career.

For Stoner this will be his last race before he heads to pastures new as he retires from the sport after the chequered flag on Sunday.

Having made up his mind for some now, the Australian commented that his feelings have not changed, but isn’t too emotional at this point regarding his retirement.

“There is to a certain degree [mixed feelings], but like I’ve said in the past this isn’t something I’ve just decided a month ago,” Stoner said. “I’ve known for a long time that this was going to be my last race.

“There aren’t too many emotions going on, we know what our decision means, so we’re going into this race like we are in the last races, to do our best at the moment, and see how we feel after the last race.

“Of course the feeling is a little bit different going into this race, not fighting for a championship, and we’re not looking to next season, so there are different feelings I suppose, to what I’m used to in the past.

“But in general we still feel pretty good for this race, and we won’t know until Monday how I feel.”
