Overview of the Swim in Different Triathlon Distances

Triathlons come in various formats, ranging from short course races to endurance challenges like the full distance, or IRONMAN. Here’s a breakdown of the different triathlon distances:

• Super Sprint: 400 meter swim (437 yards, 0.4 km, .25 miles)
• Sprint Triathlon: 750 meter swim (820 yards, 0.75 km, .46 miles)
• Olympic Distance Triathlon: 1.5 km swim (1,640 yards, 1,500 m, .93 miles)
• Half Distance (IRONMAN 70.3): 1.9 km swim (2,090 yards, 1,900 m, 1.2 miles)
• Full Distance (IRONMAN): 3.8 km swim (4,180 yards, 3,800 m, 2.4 miles)

From the Super Sprint Triathlon to the Full Distance: Choosing Your First Triathlon

If you're new to triathlon, selecting the right triathlon distance is crucial. Consider the following when choosing your first triathlon:

• Your swimming experience: If you’re new to swimming, a super sprint distance might be a good starting point.
• Training commitment: sprint races require less training time compared to an IRONMAN triathlon.
• Race goals: Want to finish your first event or push for the fastest time?
• Location and conditions: Ocean swims differ from swimming in open water lakes.
• Gear requirements: Longer races may require a wetsuit.

Short Course Triathlons: Super Sprint and Sprint

A super sprint triathlon is a great entry point for new triathletes. The super sprint distance swim is typically 400m (437 yards / 0.4km), taking place in a 50m pool swim or calm open water. In a sprint distance triathlon, the swim is followed by a 20km bike and a 5km run.

Average Times for Super Sprint and Sprint Triathlon Swim Distances

Here are the average swim times for super sprint and sprint triathlon distances:

• Super Sprint: 5-12 minutes (depending on experience)
• Sprint Distance Triathlon: 10-20 minutes

Super League Triathlon and Other Unique Formats

Super League Triathlon features shorter distances with multiple races in one event, making for an exciting format.

Understanding the Olympic Distance Triathlon Swim

Also called the "standard distance" or "international distance," the Olympic distance triathlon is the distance featured in the Summer Olympics. It features a 1.5 km swim (1,640 yards or 1,500 meters), typically in swimming in open water settings like lakes, rivers, or oceans.

Average Times for the Olympic Triathlon:

• Beginner: 30-40 minutes
• Intermediate: 25-30 minutes
• Advanced: 20-25 minutes

Once you’ve achieved your race goal of a sprint or Olympic distance race, it might be time to move on and start training for your first half or full distance event! If you’re looking to set big personal goals, check out our app with unlimited options for training, and plans personalized for you.

Exploring Longer Distances: Half Distance (IRONMAN 70.3) and Full Distance (IRONMAN)

The Half Distance Swim

A half-distance, or IRONMAN 70.3 includes a 1.9km swim (2,090 yards / 1,900m). The full distance, or IRONMAN swim (sometimes called the "iron distance") is 3.8 km (4,180 yards, or 3,800 meters). This race requires strong endurance and efficient swimming skills, especially in challenging events such as the IRONMAN World Championship, an iconic triathlon event held every year, or Challenge Roth, another prestigious event held in Germany.

An Introduction to Triathlon Swim Training

Swimming for triathlon is unique. Unlike pool racing, triathlon swimming is about being efficient, comfortable, and confident over longer distances. You won't see any 50 or 100-meter races in a triathlon! The goal is to conserve energy so you can excel on the bike and run that follow.

To start, focus on three key elements:

Swim Gear

Basic equipment for triathlon swim training includes:

• A basic training swimsuit for pool swimming.
• A well-fitting wetsuit for open water swims.
• Goggles that fit comfortably without leaking (use an untinted pair for pool swimming, and select your level of tint for race day depending on the light conditions).
• A swim cap (silicone or latex) for streamlined swimming.
• Training tools: A pull buoy, kickboard, snorkel, fins, and paddles can be helpful for developing strength and completing drills.

Technique

Mastering the freestyle stroke (front crawl) with proper breathing and body position is essential for triathlon success. Other strokes, such as butterfly, backstroke, and breaststroke, can be used to warm up and cool down or to practice certain techniques beneficial to the front crawl.

Consistency

Aim to swim 2-3 times a week to develop endurance, comfort, and a feel for the water.

Key Strategies for Training Based on Swim Distances

Below, you'll find some of our favorite quick tips about how training differs from one format or length to the next.

• Super sprint and sprint: Focus on swim technique and short sessions.
• Olympic and half-distance: Increase endurance with long swims.
• Full-distance triathlons: Train for sustained effort with open water swims.

Tips for Reducing Swim Time and Enhancing Efficiency

These simple tricks, when added to your regular swim training, can help make you a faster swimmer:

• Improve stroke technique
• Use a wetsuit if needed
• Train in open water
• Focus on endurance
• Work on breathing and sighting

Open Water Swimming: An Introduction

Most triathlon swims take place in the open water: rivers, reservoirs, lakes, and oceans. Open water swimming is a major shift from the pool. The lack of lane lines and visibility can feel disorienting, but with practice, you’ll feel right at home.

Tips for Transitioning from Pool to Open Water:

• Practice sighting: In your pool workouts, begin to practice lifting your head slightly every 4-6 strokes to stay on course.
• Swim in your wetsuit to get used to buoyancy, even in the pool.
• Train with friends or join a triathlon group to mimic race-day conditions.

Tips for Overcoming Anxiety in the Open Water

Feeling nervous about swimming in a lake or ocean is common but will get so much easier with practice. Here are a few of our favorite tips on staying calm:

• Practice deep breathing before the start.
• If panic sets in, focus on floating and staying relaxed.
• Gradually build up your confidence by swimming in calm, shallow water first.

Swim Strategies for Beginners

On race day, there are lots of things you can do to make your experience more enjoyable:

• Start at the edge of the pack to avoid the chaos of the middle.
• Draft behind another swimmer to save energy.
• Focus on steady breathing and maintaining a smooth stroke.
