April 25 was officially named ANZAC Day in 1916. It marks the first day the Australian and New Zealand troops saw military action in Gallipoli during the First World War.

If you're not so keen on the schooner marathon, there's a plethora of ways to commemorate. Here’s our rundown of how to spend ANZAC Day in Sydney.
