Schoenfelder began skating after seeing
Isabelle and
Paul Duchesnay at an ice show and switched to ice dancing after only six months in singles. Delobel and Schoenfelder were paired together in 1990 by coach
Lydie Bontemps on the suggestion of
Irina Moiseeva and
Andrei Minenkov. They won a silver medal at
1996 Junior Worlds before moving up to the senior ranks prior to the 1996–97 season. They won their first Grand Prix medal at the
1999 Skate Canada. Early in their career, they were coached by
Muriel Boucher-Zazoui in
Lyon, France.
Tatiana Tarasova and
Nikolai Morozov were their choreographers from 1998 to 2002 and their coaches from 2000 to 2002 in
Newington, Connecticut. 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. Feeling more comfortable in France, Delobel and Schoenfelder decided to return to Lyon and Boucher-Zazoui after the 2001–2002 season. They won their first national championship in the 2002–03 season. Delobel and Schoenfelder worked with choreographer
Pasquale Camerlengo for the 2005–06 season. Delobel and Schoenfelder often finished just off the podium at major events, including a 4th place at the
2006 Olympics, less than two points behind the bronze medalists. The following season, they won their only
European title but were unable to win a medal at
Worlds. Delobel and Schoenfelder did not repeat as European champions the
following year, finishing second. They then went on to win the
2008 World Championships. They were first in both the compulsory and original dance portions of the event, and second in the free dance. They considered retiring but decided to continue competing. They began the 2008–09 season with wins in all three Grand Prix appearances –
Skate America,
Trophée Eric Bompard, and the
Grand Prix Final. 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. . Delobel became pregnant during the injury layoff. She and Schoenfelder trained cautiously, with
Marie-France Dubreuil substituting for Delobel in lifts. Dubreuil, along with
Patrice Lauzon, also choreographed their final free dance. Occasional falls caused Delobel to leave the ice in late July. 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. They also skipped
French Nationals and the
European Championships in order to spend more time on training. 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. They finished sixth and retired from competitive skating. They continue to skate together in shows. Schoenfelder now coaches in Lyon. Among others, he coaches
