Are athletes narcissists looking for attention?

I ended up knowing two athletes. They are somewhat semi-obscure athletes and do endurance, marathon. Though I admire the fact that they can do what they do, I noticed that whenever they write on their social media about the event/race they've been through, they seem to look for attention, and put extreme emphasis on how much they suffered and how they felt instead of the achievement. Every single time!!

I cannot provide you with the exact pages, because they're not in English. But am I wrong to feel annoyed when I see that their comments stress out how they suffered and struggled?
