[2][4] While practising a lift at French Nationals in December 2001, Delobel tore an abdominal muscle, keeping her off the ice for six weeks and forcing the team to miss the European Championships.

[5] Delobel and Schoenfelder often finished just outside the medals at major events,[6] including a 4th place at the 2006 Olympics, less than two points behind the bronze medalists.

During their gala exhibition performance at the Grand Prix Final in December 2009, Delobel suffered a shoulder injury and underwent surgery on 5 January 2009, causing them to miss the remainder of the season.

[11] Delobel's son was born in October and she returned to the ice toward the end of the month, beginning three-a-day sessions and intense physical training in November.

[11] The two returned in time for the Vancouver Olympics, competing just four-and-a-half months after she had given birth and announcing it would be their final competition.

[16] Delobel married Ludovic Roux, a bronze medalist at the 1998 Olympics in team Nordic combined, in June 2009, and their son, Loïc, was born on 2 October 2009.
