Check for mistakes in GCSE practice essay? :)

昨年、朝ごはんを食べて、ロンドンへ行きました。 weird
先月、朝ごはんを食べて、ロンドンへ行きました。weird
先週、朝ごはんを食べて、ロンドンへ行きましたweird
昨日、朝ごはんを食べて、ロンドンへ出かけました。OK
先月、朝食後ロンドンへ向けて出張しました。OK ??　weird ???

なんにちかまえに、あさごはんを食べたあと、ロンドン へ行きました。OK
このまえ、あさごはんを食べたあと、ロンドンへ行きま した。OK

It is very difficult to analyze and explain why weird, but it is weird, really.

My ears simply refuse to take the combination of 「先週」 and 「朝ご飯を食べた」. I would have found no issue had OP opted to use a specific day like 「先週の土曜日」. You may confirm this with any Japanese-speaker that you trust.

Ah! My mistake. I see where we were getting our wires crossed!

Yeah, if there were no context about "last week" being "last weekend," then definitely "last week I ate donuts and went to Austin" does sound weird.

I think I was operating under a "student" assumption that travel would have had to have happened on the weekend.

So yeah, you're right!

And that "have had to have" above in this post? That's some next-level weird-yet-correct English going on there! It even gave me pause when I was writing it—"is that correct? humm...yeah it is *clicks save*"
