Under the "Countries Visited" section it says "been lucky to run on all seven continents, including antarctica!", but it doesn't look like they've been to Australia.
Edit: also, they pulled the data from strava. It’s possible they forgot to record their Australian run(s) in strava for some reason
there aren't that many of us (that have run on antarctica, vs king george island).
Or NZ at the least. Hawaii isn't on the content. You've got only one continent to go before you can check that box.
I have 100% confidence you'll do it!
I ran every day for a year, and kinda wished I had kept going (though I only managed 3 continents in that year).
