[9] Katzberg enjoyed early success on the international competitive circuit in 2023, notably winning gold when the Diamond League held a promotional mixed-gender hammer throw event at the 2023 Meeting de Paris.

[11] Katzberg's victory made him both the youngest ever men’s hammer throw medallist and world champion, and the first Canadian man to win a medal in the event.

[15] To start his 2024 season, Katzberg threw 84.38 m on April 20 at the Kip Keino Classic in Nairobi, Kenya, a new Canadian and NACAC area record the longest hammer throw by anyone since 2008, moving him to ninth on the all-time list.

[16][17] Named to his first Canadian Olympic team, Katzberg entered the hammer throw event as the title favourite, and finished first in the qualification round.

[21] Shortly after his victory, Katzberg traveled to attend a training camp in Slovakia, but returned to Paris a few days later upon being named Canada's co-flagbearer at the closing ceremony, alongside triple gold medalist swimmer Summer McIntosh.

[22] At the end of the year, Katzberg received the Lionel Conacher Award as The Canadian Press' choice for the nation's top male athlete of 2024.
