Like a lot of sports, triathlon is full of rules. For example, you’re not allowed to cut the course, have a motor on your bike, curse at officials, punch a rival, or, most craven of all, have fewer than three safety pins on your race number in France.
However, and particularly helpful for beginners, there are plenty more unwritten rules that we need to be aware of. Some of them, we’ve helpfully outlined below:
General Unwritten Rules of Triathlon
1. Procrastination is Expensive — Swear you’ll sign up at the early bird rate, procrastinate, and then find out your chosen Ironman sold out within 24 hours anyway.
2. Forever Alone — The training paradox. The more you do triathlons, the more all your friends are triathletes, and the more you will train alone.
3. You Are Not Kristian — The Norwegian Method is to train more hours in a day than you do not train. For more training methods, see YouTube.
4. The Devil’s in the Details — Dedicate 20 hours a week to training for three months in the lead up to your A race. Spend zero minutes working on transition.
5. Shelve Twitter Hate — Write a mantra on your water bottle and start an Instagram account for reels, stories, and collabs. Don’t be an angry person on Twitter. That’s not cool.
6. Match at All Costs — Never sacrifice style for performance. Color-coded kit and equipment are essential, unless you’re going for garish retro, which is an acceptable look for 2026 only.
Race-Week Rules Triathletes Should Live by
7. Weather or Not? — Check the weather forecast and water temperature before checking the weather forecast and water temperature, and then solicit opinions on what the weather and water temperature are likely to be on race day.
8. Wetsuit Your Worries Away — Convince yourself you can’t swim without a wetsuit/won’t be able to get your wetsuit off if it’s a wetsuit swim.
9. Experience Equals Complacency — The athlete guide must be studied with a focus that inversely correlates to how many races the athlete has done.
10. Selfie First, Reality Later — Take a selfie with the giant M-Dot “Ironman Is In Town” sign. Post this to social media as soon as you land, feigning a smile because although you’ve arrived, your bike hasn’t yet followed.
Race-Morning Rules
11. Hell’s Bells — Set three alarms minimum and then wonder why the first of them is going off as you force-feed yourself rice because you couldn’t sleep anyway.
12. Nothing Matters as Much as Everything — Take time to stare at your race tattoo, realize the transfer has only half stuck, and have a mild panic by convincing yourself you’ll be disqualified before the start.
13. Apply Liberally — Use sunscreen, making sure you miss a key patch of skin. It will show more of your suffering.
Unwritten Rules for Race Morning

14. Pay it Forward — In the name of karma, offer to: a) Zip up someone’s wetsuit; b) Lend them a bike pump (even if it’s not yours); c) Thank everyone you see profusely and wish them all a great day.
15. Ride the Intake Earthquake — Increase your volume of carbohydrates per hour exponentially with the same dedication you had when you raced 15 years ago and were insistent on using only your 5% body fat as a fuel source.
16. Be a Bathroom Banterer — Talk with bravado about your trained ability to both pee in the swim and on the bike while you stand for an hour in a revolving porta potty line.
During the Triathlon Race Unwritten Rules
17. What’s Good for the Goose is Good for the Gander — Oops! You punched someone in the eye in the swim completely by accident. Also, the breaststroker you got stuck behind at the first buoy deliberately kicked you in the face.
18. Meditate on Aquatic Paradoxes — During the swim, reflect on: a) Whoever learned to swim as a kid is basically a cheater. Or b) “Why do triathletes swim so freaking slowly?”
19. Style Reigns — Replace existing drink bottles on the bike with those from the on-course sponsor. Call bottles bidons if you’ve ever watched a clip of the Tour de France.
20. The Refs Need You (Really) — Become militant about drafting and shout obscenities at a pack who: a). Aren’t in the race anyway; b) Are out for a gentle social weekend ride; c) Are still moving faster than you.
21. Ride the Highs and Lows — When you are riding downhill, you think you will win. When you are riding uphill, you think you will come last.
22. Roll the Dice — Breathe a sigh of relief when you complete the bike leg without puncturing because you haven’t practiced changing tires for five years.
23. Don’t be Patronizing Pat — If you pass someone on the run, resist the urge to tap them encouragingly on the back. One athlete’s chirpy come-on is another athlete’s patronizing pat. And if you must do it, always avoid the backside.
24. Leave Self-Awareness Back at the Hotel — Do something in the finish chute that in any other walk of life you would find cringey. This includes sweaty mess marriage proposals to a long-suffering partner who has a cooked neck from staring at a race tracker for the past 14 hours.
Post-Race Friendly Reminders
25. Be Congratulating Carl — Always congratulate the first person you see at the finish. However hollow-eyed your expression or soiled your tri suit. It’s your duty to have that mutual moment with a complete stranger.
26. The Rules of Race Photography are Unbending — Acknowledge that official race photographs only ever capture: 1. Grotesque faces. 2: When you “briefly” sat up out of aero. 3. Ugly heel strikes
27. You’re the Best — Use multiple filters of the race results, including but not limited to age-groups, disciplines (including transitions), and nationalities to claim a top-10 position at some aspect of your race. If you rode a road bike, you can also disqualify everyone who rode a TT/tri bike.
28. Brutality Reigns — Include the word “brutal” at least three times during any social media race report.
29. There Are Steps — Once you have finished your first sprint triathlon, take the following actions (in order): a) Sign up for an Ironman, b) Sign up for a Hyrox, c) Advertise your coaching services.
30. Triathlon = Procrastination (Always) — Finally, swear you’ll sign up at the early bird rate, procrastinate, and then find out your chosen Ironman sold out within 24 hours anyway.
