26.2 Things to Know Before Running Your First Marathon

So, you’re thinking about running your first marathon? You’re not new to running, but the 26.2-mile journey is still uncharted territory. This isn’t about checking off a bucket list item—it’s about doing it right.

Here are 26.2 things every experienced runner should know before lining up for their first marathon.

1. Marathon training is not just longer 10K training. It’s a different animal. Volume increases dramatically, yes, but so do the mental, logistical, and nutritional challenges.

2. Long runs are your cornerstone. Skip intervals if you must, but never miss a long run. They build endurance, test your fueling, and toughen your mind.

3. You need to train your gut. Gels, chews, hydration mixes—your stomach needs time to adapt. Practice fueling on long runs like it’s race day.

4. Not all miles are equal. Running junk miles at a slow pace may build aerobic capacity, but purposeful training beats mindless mileage.

5. Strength training helps you go the distance. Two sessions a week can prevent injury and improve performance. Focus on core, glutes, and posterior chain.

6. Tapering is not slacking. A proper taper (2-3 weeks) allows your body to absorb training. Resist the urge to squeeze in more.

7. Marathons are a fueling game. If you hit the wall, chances are you under-fueled. Aim for 30-60g of carbs per hour.

8. Sleep is your secret weapon. More than ever, sleep quality and quantity matter during peak training and race week.

9. Hydration is not just water. Balance fluids with electrolytes. Overhydration without sodium can lead to hyponatremia.

10. Blisters, chafing, black toenails—expect them. Don’t let small discomforts become race-enders. Body Glide and well-fitted gear are your allies.

11. Don’t chase paces on your long runs. Long runs build endurance, not speed. Save the hero workouts for race day.

12. Trust your training, not your watch. Garmin can lie. GPS errors happen. Learn to run by feel, especially in crowded starts.

13. Learn the course. Elevation, aid station placement, turns—knowing what’s ahead helps you strategize.

14. Race week is not the time to experiment. Stick with familiar gear, meals, and routines. That new energy drink? Test it another day.

15. You won’t sleep well the night before. That’s fine. Bank your rest two nights before the race.

16. The wall is real. Usually around mile 20. Prepare mentally. Break the race into segments and keep your mind busy.

17. Carry your own nutrition. Aid stations might not have what you need. Or they’ll run out.

18. Don’t go out too fast. The marathon punishes the overconfident. If you feel great at mile 10, you’re pacing right.

19. Weather matters—but your plan matters more. Yes, heat slows you down. But poor pacing or bad fueling can derail your race regardless.

20. Post-race recovery starts before the finish line. Get carbs and protein in within 30-60 minutes. Keep moving after you cross.

21. Prepare for post-marathon blues. You’ve trained for months. After the high fades, motivation might drop. Plan what’s next.

22. Race day is emotional. You’ll cry at the finish. You’ll see people overcome huge odds. Let it move you.

23. Pick the right shoes. Lightweight racers might not be best if they destroy your feet over 26 miles. Comfort wins.

24. Anti-blister socks are worth the money. Double-layer, seamless toe, moisture-wicking. Invest.

25. Track fatigue, not just pace. Heart rate, perceived effort, and sleep patterns tell you more than splits.

26. Respect the distance. Even elites can have a bad marathon. It humbles everyone. Finish strong, not broken.

26.2 You only get one first. You’ll never forget it. Make it memorable, not miserable. Run smart, stay patient, and savor every mile.

Marathon day will test everything you’ve built—your endurance, strategy, grit, and patience. But if you arrive prepared, it can also be one of the most powerful experiences of your life. Good luck, and enjoy the journey to 26.2.
