The daffodils are blooming, the days are getting longer, and that nervous flutter in your stomach? Yep, it can only mean one thing – spring marathon season is here! Whether it’s your first ever 26.2 or you’re coming back for more, one thing’s for sure – marathon season has a vibe all of its own. You’re about to embark on a journey of self-discovery that will make you question your sanity at times. As someone who’s been there, done that (and has the medals to prove it), I’m here to share 26 things I wish I knew before my first marathon.

1. Training is non-negotiable

Sounds obvious, right? But you can’t fake your way through 26.2 miles. A consistent training plan is your best friend – follow it and trust it.

2. You don’t have to run every day

Rest and recovery are just as important as your long runs. Skipping a rest day doesn’t make you hardcore, it just makes you more likely to get injured.

3. Your long run is sacred

These are the ones that build your endurance and mental grit. Protect them like your life depends on it (because your race might).

4. Chafing is not a joke

Body glide, Vaseline, or anti-chafe balm – whatever your weapon of choice, use it. Generously. On places you didn’t know could chafe.

5. Not every run will feel good

Some days, your legs will feel like lead and you’ll question everything. That’s normal. Keep showing up.

6. Invest in decent kit

You don’t need top-of-the-range everything, but a good pair of running shoes (fitted properly!) and moisture-wicking gear will make all the difference.

7. Don’t try anything new on race day

Don’t be wearing new trainers, trying new gels or a new breakfast on race day. Today is not the time for experimenting. Trust me on this.

8. You will talk about running constantly

To friends, to colleagues, to strangers in the queue at Tesco. It’s like a switch flips in your brain.

9. Tapering feels weird – really weird

Cutting back on your mileage in the final weeks feels counterintuitive, but it works. Your body needs the rest before the big day.

10. “The wall” is real… but beatable

Usually around mile 20. It’s physical, it’s mental, and it’s brutal. Fuel early and often, and have a mantra ready.

11. Fuel, fuel and fuel!

Practice taking on gels, chews, or whatever works for you during long runs. Don’t wait until marathon day to figure it out.

12. It’s okay to walk

Walking doesn’t mean you’ve failed. Sometimes walking through water stations or up steep hills is the smartest move.

13. Spectators are magic

A kid giving you a high five or someone shouting your name at mile 22 can give you a boost like no gel ever could.

14. You’ll cry

Maybe during training, maybe at the start line, definitely at the finish. Let it out – it’s emotional for a reason.

15. Toenails may be lost

RIP big toenail. We had a good run. (Literally.)

16. Carb loading is not an all-you-can-eat pasta pass

It’s strategic, not a food coma. Gradually increase carbs 2–3 days before, but don’t go overboard the night before.

17. Weather is a wildcard

You might train in drizzle and end up racing in blazing sun or a hailstorm. Prepare for anything and everything.

18. Pacing is crucial

Go out too fast and you’ll pay for it later. Run your own race. Trust your training, not the person sprinting past you at mile 3.

19. Marathon brain is real

You’ll forget how to do basic maths mid-race. Like what mile you’re on. Or your own name. Don’t panic.

20. Practice your race kit

Do a few long runs in your exact race-day outfit, right down to socks and sports bra. Avoid surprises (and blisters).

21. Race photos are humbling

You didn’t know your face could do that while running, did you?  It’s fine. Smile when you see the camera if you can, but no pressure!

22. You don’t need to run 26.2 miles in training

Most marathon plans max out around 20 miles. This is normal. Trust that the adrenaline (and the crowd) will carry you through the rest.

23. Plan your post-race exit

You’ll finish full of emotion… and then immediately need snacks, warmth, and somewhere to sit down. Plan accordingly. Pack some flip flops in your bag – you’ll thank me at the finish!

24. There’s a reason people keep coming back

Even after swearing “never again,” you’ll probably find yourself browsing for your next race within a week.

25. The medal hits different

It’s not just metal – it represents every early morning, every run in the rain, and every time you didn’t quit. Wear it proudly.

26. You are capable of so much more than you think

Crossing that finish line will change how you see yourself. Forever. You’ve got this.


Whether you’re weeks away from your first marathon or you’ve just signed up on a whim (we’ve all been there), I hope these little bits of wisdom help you feel more prepared, excited, and maybe even a little less nervous. One thing I will warn you about: the post-race shuffle and stairs will feel like your worst nightmare! But take it easy, give yourself time to recover, and remember that you’ve achieved something incredible. Good luck, and enjoy the journey!
