10 Common Mistakes New Triathletes Make (and How to Avoid Them) 🏊‍♂️🚴‍♀️🏃‍♂️

Starting your journey as a triathlete is exciting and challenging in all the right ways. You're learning to master not one, but three sports—swimming, cycling, and running—while juggling training schedules, nutrition, and mental preparation. It’s a lot to take in, and like all beginners, you’re bound to make a few mistakes along the way. 😅

But don’t worry—you’re not alone! Many new triathletes stumble over the same hurdles, and with the right knowledge, you can sidestep those common missteps. Here are the 10 most common mistakes new triathletes make and, more importantly, how to avoid them.

1. Skipping Rest Days 🛌

Mistake: It’s easy to think that the more you train, the better you’ll become. Many new triathletes push themselves to the limit, training seven days a week without proper rest. Unfortunately, this often leads to burnout or injury.

How to Avoid It: Rest is part of training. Your muscles need time to recover and grow stronger, and your body needs rest to avoid injury. Incorporate at least one full rest day a week, and don’t be afraid to take more if you feel overly fatigued. Remember, rest days make you stronger, not weaker.

2. Not Practicing Transitions ⏱️

Mistake: The transition from swimming to biking (T1) and from biking to running (T2) is often an afterthought for beginners. They focus on the three sports but forget that time lost fumbling with gear or feeling disoriented between disciplines can make or break their race.

How to Avoid It: Dedicate time to practice your transitions. Set up a mini transition area at home and practice getting out of your wetsuit, into your bike shoes, and off the bike into running gear. The more familiar you are with the process, the smoother and quicker your transitions will be.

3. Ignoring Nutrition 🥗

Mistake: Many beginners think that as long as they train hard, what they eat doesn’t matter. But poor nutrition can lead to low energy, slow recovery, and performance plateaus.

How to Avoid It: Treat your body like the finely-tuned machine it is. Focus on eating a balanced diet rich in whole foods—carbs, proteins, and healthy fats. Pre-race nutrition is just as important. Experiment during training to find out what works best for you, and never try new foods on race day!

4. Going All Out in Training Every Time 💥

Mistake: Many new triathletes believe that every workout should be at maximum effort, but this often leads to fatigue, injury, or burnout. Pushing yourself too hard every day doesn’t give your body the time it needs to recover.

How to Avoid It: Structure your training plan with a mix of easy, moderate, and hard workouts. Not every session should be intense. Stick to your training zones, and listen to your body. Easy days are essential for building endurance, and hard days should be reserved for intervals or race-pace efforts.

5. Skipping Open-Water Swim Practice 🌊

Mistake: Training in a pool is great for technique, but race day will likely involve open water. Many beginners assume that if they’re strong in the pool, they’ll be fine in open water. However, the lack of lane lines, currents, and visibility can throw even seasoned swimmers off.

How to Avoid It: Try to practice in open water at least a few times before race day. Get comfortable with the sensation of swimming without walls, sighting your landmarks, and navigating waves or currents. Confidence in open water is a game-changer come race day.

6. Wearing New Gear on Race Day 👕👟

Mistake: Race day excitement often leads to one of the biggest no-nos—trying out new gear for the first time. Whether it’s a new wetsuit, shoes, or bike shorts, wearing unfamiliar gear can lead to chafing, blisters, or worse.

How to Avoid It: Never try anything new on race day. Every piece of gear you plan to race in—shoes, trisuit, goggles—should be well-tested in training. Make sure everything is comfortable and that you’re familiar with how it fits and feels during your workouts.

7. Underestimating the Importance of Hydration 💧

Mistake: Many new triathletes forget to hydrate properly during training or don’t think about it until race day. Dehydration can cause fatigue, cramps, and even serious health issues like heatstroke.

How to Avoid It: Hydrate well before, during, and after training sessions. As a rule of thumb, aim to drink 16–20 ounces of water two hours before a workout and continue to sip water throughout the session. For longer workouts, consider adding electrolytes to your hydration plan to replace what you lose through sweat.

8. Not Pacing Yourself on the Bike 🚴‍♂️

Mistake: New triathletes often get overly excited during the bike leg and go all-out, only to realize they have nothing left in the tank for the run. This can ruin your race strategy and cause you to hit the dreaded “wall.”

How to Avoid It: Pacing is key. Use a heart rate monitor, power meter, or simply rely on perceived effort to ensure you're not overexerting yourself on the bike. Remember, you still have to run after the bike leg! A steady, controlled pace will leave you with enough energy for a strong finish on the run.

9. Skipping Brick Workouts 🏃‍♀️

Mistake: The transition from cycling to running is one of the most challenging parts of a triathlon. Your legs feel heavy, and your stride feels awkward. Skipping brick workouts (where you practice cycling followed immediately by running) can make this transition even harder on race day.

How to Avoid It: Incorporate brick workouts into your training plan. Even if it’s just a short run after a long bike ride, practicing the transition from bike to run will help your legs adjust to the change. This will make the run portion of your race much smoother and more manageable.

10. Not Listening to Your Body ❤️‍🩹

Mistake: Many beginners push through pain or discomfort, thinking it’s part of the process. While some soreness is expected, ignoring persistent pain can lead to serious injuries.

How to Avoid It: Listen to your body. There’s a difference between pushing through discomfort and pushing through injury. If something doesn’t feel right—whether it’s sharp pain, swelling, or prolonged soreness—take it seriously. Rest, adjust your training, and seek professional help if needed. Remember, it’s better to take a few days off than to be sidelined for months.

Final Thoughts: Learn from the Mistakes of Others 🏅

Training for your first triathlon is a thrilling experience, but it’s easy to make mistakes along the way. The good news? By being aware of these common pitfalls, you can avoid them and set yourself up for success.

Remember, triathlon training is a marathon, not a sprint. Take it one step at a time, listen to your body, and most importantly, enjoy the journey. Every mistake is an opportunity to learn and grow as an athlete.

Good luck out there, and keep moving forward! 🚀
