Ilya Mironov

Mironov began learning how to skate in 2005. He competed internationally as a single skater on the junior level from the 2014–15 figure skating season through the 2017–18 season, after which he switched to pairs and teamed up with his current partner, Diana Mukhametzianova. For their first two seasons together, Mukhametzianova/Mironov only competed domestically, and finished 6th at the 2019 Russian Junior Figure Skating Championships.

Mukhametzianova/Mironov made their junior international debut at the 2019 JGP Russia. They placed third at the event behind fellow Russian competitors Kseniia Akhanteva / Valerii Kolesov and Iuliia Artemeva / Mikhail Nazarychev. At their second assignment, the 2019 JGP Croatia, the team placed second, again behind teammates Artemeva/Nazarychev, and with 24 qualifying points advanced a spot to the 2019–20 Junior Grand Prix Final. The pair competed once more before the Final, earning a silver medal in the junior event at the 2019 Volvo Open Cup behind Apollinariia Panfilova / Dmitry Rylov.

At the 2019–20 Junior Grand Prix Final, Mukhametzianova/Mironov delivered two clean programs to win the silver medal behind Panfilova/Rylov. The team won the free skate, but were unable to fully make up the margin set by the gold medalists in the short program. They set personal bests in all segments of competition at the event.

Despite qualifying, Mukhametzianova/Mironov elected to sit out of the 2020 Russian Figure Skating Championships due to fatigue from the Junior Grand Prix Final. They next competed at the 2020 Winter Youth Olympics, where they again finished second behind Panfilova/Rylov. At the 2020 Russian Junior Figure Skating Championships, Mukhametzianova/Mironov finished just off the podium in fourth and as such narrowly missed being named to the 2020 World Junior Figure Skating Championships.
