So I'm gearing up for my first 50k and honestly, I'm terrified I'm gonna do something dumb and ruin the whole thing. Like, should I avoid the classic rookie move of going out too fast? Or is there a specific fuel I should totally NOT be shoving down my throat mid-race? Hit me with your worst horror stories, I need the deets!

  One classic mistake to avoid is not sticking to your fueling plan. I once tried some new energy gels on race day, and let's just say it didn't end well for my stomach. Stick with what you know works for you during training.

    Facts! Don't forget to plan your nutrition strategy well ahead of race day. Find your carb-to-protein ratio that keeps you performing well. For me, a 3:1 ratio works great during long runs. It's all about what your body can handle.

  Going out too fast is a huge rookie move. I remember my first race, I felt like a hero sprinting ahead, but I hit the wall hard around mile 20. The best approach is to start at a comfortable pace and gradually increase if you're feeling good. It's all about that endurance, especially for a 50k.

    Make sure you're careful with hydration too! Overhydrating is a real thing. I know it sounds weird, but I've seen runners cramp up because they took in too much water and electrolytes. Balance is key.

    This! And seriously, don't experiment with new shoes or gear on race day. I tried a different pair once, and my feet were screaming by mile 15. Stick to your trusty setup, man.

  Ngl, the real horror is when you forget to fuel mid-race. My buddy tried to save time and skipped his snack. Dude was out there hallucinating about pizza by mile 25. Don't be that guy.
