Well, there's nothing to be confused about regarding Danish names. It's very simple; it varies.
Here are a few examples using riders in this race:
For example, we have 'Andreas Lorentz Kron', who is referred to as just 'Kron'.
Then we have 'Tobias Lund Andresen', who is referred to as just 'Lund'.
There's also 'Anthon Charmig', who is referred to as just 'Charmig', because he only has those two names.
Finally there's 'Mikkel Norsgaard Bjerg', who is referred to as just 'Bjerg'. (Also, he's only had the name 'Norsgaard' since 2021.)
But all of these are consistent with Scandinavian or Danish naming customs. So names can still be explained. No confusion needed if you know the customs (which admittedly are way more varied than, say, Spanish names).
Kron has double first name, like f.ex. Jean Marie in French. Or Kurt Asle in Norwegian.
Lund has the weird Danish patronym at the end, which is what I referred to when contrasting with Norwegian names. Seems like a lot of Danes have it. Søren Kragh, for example. Or Magnus Cort. It's extremely rarely used in Norway, and in the very rare cases where it is, it's before the actual surname as opposed to after it.
Charmig just has one surname, presumably his father's name, which is still very common in Norway too.
Bjerg has two surnames, probably one from each parent. So it's similar to Martin Urianstad Bugge. Or Tobias Halland Johannesen (where Johannesen is not a patronym but a normal surname that originated as a patronym in the 1800s when everyone were required to have a surname. That part could be confusing I guess. But actual patronyms are so rare in Norway that they can basically be disregarded).
Edit: Okay, so if Bjerg only has had Norsgaard since 2021, it has to be his wife's name. Which is also a normal way to get two surnames, although it's not as common for the man to change/add to his name as it is for the wife.
