Triathlon Basics for Beginners

What are the Distances of a Triathlon?

A triathlon is a multisport race that includes swimming, biking, and running in a single event. The order is usually always swim, bike, and run, though some innovative, alternative formats do exist. An organizer can put on a triathlon of any distance they want to, but here’s a breakdown of the most common, sanctioned distances:

• Sprint Triathlon: ~750-meter swim, ~20-kilometer bike ride, and ~5-kilometer run.
• Olympic Distance: ~1.5-kilometer swim, ~40-kilometer bike, and ~10-kilometer run.
• Half-Distance (Ironman 70.3): 1.9-kilometer swim, 90-kilometer bike, and 21.1-kilometer run.
• Full-Distance (Ironman): 3.8-kilometer swim, 180-kilometer bike, and 42.2-kilometer run.

For new triathletes, starting with a sprint triathlon is the best choice. It’s achievable with an 8-week training plan and gives you a taste of the sport without being overwhelming or completely dominating your schedule.

Choosing Between Sprint and Other Triathlon Distances

The sprint distance is perfect if you are new to endurance sports, have limited time to train, and want to avoid overtraining or burnout.

If you’re aiming for a half or full distance race, be prepared for a bigger time commitment and a more advanced training plan. But for most new triathletes, the sprint distance is the sweet spot for balancing challenge and fun.

Essential Triathlon Gear You’ll Need

One of the best things about training for a triathlon is that you don’t need fancy gear to get started. Focus on essentials, and upgrade as you go. Here are some important things to remember when it comes to gear and upgrading:

Start with What You Have

Any bike is better than no bike—whether it's a mountain bike, road bike, or even a borrowed one. Focus on riding and training over obsessing about expensive upgrades early on.

Prioritize Budget-Friendly Upgrades

Big performance gains can come from small investments such as clip-on aerobars or a proper bike fit. There's no need to spend thousands on high-end bikes and components right out of the gate.

Optimize for Practicality

Triathlon is a personal journey, and enjoyment is key. Purchase and upgrade only the gear that fits your budget and needs.

Swimming Essentials

• Swimsuit or tri-suit
• Swim cap
• Goggles
• Optional: Wetsuit (for open-water events or colder conditions)

Biking Essentials

• Any bike: a road bike, mountain bike, or hybrid bike will work to start. (Check out this article for specifics on triathlon bikes.)
• Helmet (required for safety)
• Water bottle for hydration
• A sport watch that can track your heart rate and pace at minimum, with options to include cadence, and power, if needed. (Your workouts can be sent from the MOTTIV app right into your watch to guide you step by step through your workouts.)
• Optional: Clip-on aero bars, cycling shoes, and clip-in pedals

Note: The bike is the most gear-intensive discipline in the sport. As you progress, you'll want to consider additional add-ons such as:

• Aero helmet: An aero-road helmet offers a speed boost of about 1 km/h over traditional helmets. Opt for models designed for both training and racing.
• Aero wheels: Deep-rimmed wheels (50mm or more) can provide significant aerodynamic benefits. However, they require skill and confidence to handle effectively.
• A triathlon-specific bike: Tri bikes are more aerodynamic and comfortable for long-distance riding but should only be purchased when a long-term commitment to the sport is clear. Entry-level tri bikes combined with other upgrades often perform comparably to high-end models.
• Power meter: Useful for monitoring effort but not essential early on. Athletes should first develop a strong sense of effort through heart rate and perceived exertion.
• Indoor trainer: A smart trainer paired with software like Zwift can make indoor training more engaging and consistent.
• High-end components: Groupsets like Shimano Ultegra or Dura-Ace enhance shifting precision but provide marginal performance gains compared to mechanical setups.

Running Essentials

• Comfortable running shoes (visit a running store for expert fitting)
• Running shorts or a tri-suit

Core Workouts and Techniques for Triathlon Training

Swimming in Open Water vs. Pool Training

For new triathletes, swimming can seem intimidating at first. Here’s how to prepare:

• Breathing is foundational to swimming confidence and performance. By mastering breathing techniques through drills and a calm, consistent approach, triathletes can eliminate panic and enjoy the water.
• Prioritizing comfort in breathing allows for focus on advanced techniques, ultimately leading to faster and more efficient swimming.
• To get ready to transition to the open water, practice in a pool first to master swimming techniques and breathing.
• Transition to open water 2-3 times before your first race to get used to waves, currents, and lifting your head to sight (see where you're going).

We know that learning to swim as an adult can be one of the biggest challenges for aspiring triathletes. Our book Triathlon Swimming Foundations is a great place to start if you want proven instructions on how to become comfortable in the water. We’ve helped thousands of adults learn to swim!

Bike Training Tips

Most people find that they have an easier time getting into bike training. With regards to bike workouts, we recommend performing one low-intensity bike ride every single week, where you start with however long you're able to bike for and then build up the length of time by eight to 10% every week to build endurance.

We recommend making the second session a harder ride, with intervals of one to eight minutes and with rest periods of one to eight minutes. Follow this over a number of months, and you will build up your endurance and speed on the bike.

Learn more about bike training in our book Triathlon Bike Foundations, including basic cycling principles, drills, and essential workouts.

Beginning Run Training

When it comes to running, the main challenge is building endurance to run longer and faster without spiking your heart rate. Start with a walk-jog program: jog as long as you can, then walk for 2.5 minutes. Gradually reduce the walking interval and extend jogging time by 10 seconds per session. In about six weeks, you'll be able to run continuously.

Next, focus on two weekly runs. The first should be a low-intensity run, where you build endurance by running at an easy effort and increasing duration by 8–10% weekly. The second should be an interval run, where you work on your speed with intervals of 1–8 minutes, matched with rest periods of the same length. Gradually increase interval duration and pace while shortening rest.

As you get closer to your race, practice running directly after a bike session to simulate what you’ll need to do on race day. This is called a brick workout, and will help you work on running efficiency. Use brick runs to learn how to pace—start slow and build speed.

Triathlon Nutrition Basics

How to fuel your training sessions and your races is something that you’ll refine as you become more experienced in the sport. The products that work for some may not work for you. To get started, use the below calculator to estimate your calorie needs based on weight, speed, and race distance. During training and races, fuel consistently every 15–30 minutes to maintain energy levels.

Preparing for Your First Race Day

The training is done and race day is here! Don’t worry if you feel nervous—it’s extremely common to experience anxiety ahead of your big event. Also, it means you care! Here are some of our key tips for making race day a smooth and successful experience, from the moment you arrive on-site to the finish line you’ve been visualizing for months.

Race Morning Tips

• Lay out all the gear you'll need for your race the night before.
• Eat a carb-rich breakfast low in fat, protein, and fiber.
• Put your timing chip on your ankle, if you received one at check-in, before you leave the house.

What to Expect on Race Day

• Arrive early to set up in transition.
• Visualize the course: where will you enter the water and exit, run into the first transition, bike out, bike in, run out, and run back in?
• Follow the race day flow: swim, bike, and run, executing all your hard training.

Managing Pre-Race Nerves and Mindset

• Practice mindfulness techniques like deep breathing.
• Focus on your training, and remember—this is about finishing, not perfection.
