The Sydney Marathon medal features recognisable landmarks like the Opera House and Harbour Bridge, but users noticed the stadium engraving resembled Munich's Allianz Arena rather than Sydney's Allianz Stadium. The error sparked humour online, with Sydney Marathon confirming runners would receive the medal as-is, calling it "beautiful" and "a little more unique." Germany's Allianz Arena joined in on Instagram, joking they "didn't have that on our bingo card" and noting shared traits like unique architecture. The reverse side of the medal displays a gold and indigo pattern by First Nations artist [PERSON_NAME], who confirmed he was not involved in the stadium face design.

Around 40,000 runners will participate in the event on 30 August, selected from over 120,000 ballot entries. Organisers highlighted record participation and fundraising success, praising the event's spirit despite the mix-up.
