That's great. Running a marathon (I've already done a half) and visiting Antarctica (I've already done all but one of the other continents) are both on my to do list. I probably shouldn't tick them both off in one go, though.

Awesome! If you wanted to tick them both off in one go, I totally think you could do it... ;)
