Mukhortova and Maxim Trankov trained in the same practice group under coaches Ludmila Velikova and Nikolai Velikov, but with different partners. Mukhortova first competed with Pavel Lebedev during the 2001–02 and the 2002–03 season, skating with him on the ISU Junior Grand Prix and finishing fourth at the 2002 and 2003 World Junior Championships. The pair had frequent arguments but due to good results, Mukhortova initially declined to switch partners, however, a year later in 2003, she accepted Trankov's suggestion to skate together.
