A few things are fueling this fire. First, we’ve all been sitting on our couches for a few years, and now we need to prove we can still move. Running a marathon is the ultimate “I’m still alive” party trick.
Second, social media makes it look too good. You see someone crying at the finish line, holding a medal, and you think, “I want that dopamine hit.” It’s like watching a cooking show and thinking you can make a soufflé. Spoiler: you probably will, but it hurts.
