From Valmiera, Caune won the silver medal in the 5000m at the 2021 European Athletics U20 Championships in Tallinn, whilst just 16 years-old.

At the 2023 European Indoor Championships held in Istanbul in March 2023, Caune qualified for the final, where she set a new Latvian U20 record for the 3000m, clocking 8:56.88 to finish in eleventh place.

[11] Caune then won a gold medal in the 5000 meters at the 2023 European Team Games running 15:15.21 in the Second Division race.

[12] On July 16, 2023, in Silesia, Caune made her Diamond League debut and finished in seventh place in the 3000m distance, running 8:39.78 to break the Latvian national record.

She used a bold strategy—heading straight to the front of the pack and not slowing down as the distance between her and her competitors increased—that helped her advance to the next round of the 5000 metres.

However, prior to the final event, Caune withdrew due to a pelvic injury that had been present from the past few days.
