She’s said before that she only said gold about the marathon to basically have a big goal and show she was serious/get attention, I think she always knew it was far-fetched. But as an already Olympic Gold holder it’s a lot less ridiculous than other people saying it. anyway it worked because people argued about it and it got her the video views etc. I also remember the 2:19 quote and I’m pretty sure she was joking, saying she was sad she wasn’t in 2:19 shape was obviously because it wasn’t likely not because she actually thought she could or ever would. She picked 2:19 as a pie in the sky number.
I can find people irritating too but I’m pretty sure one of those comments was an intentionally overreach goal and the other one was just a joke.
What I find weird is that she’s so obsessed with marathon, she ran those really good track 5000m and 10,000m without much run-specific training yet has shown no interest in those distances since when comparatively she fared much better (and it also appears high mileage isn’t working for her). I know there’s a lot of US female talent in those distances but I think it’s more realistic than marathon
