Triathlon Types & Distances Comparison
Triathlons come in various distances and formats to suit different fitness levels and goals. This comprehensive guide compares the most common triathlon types from beginner-friendly Super Sprint distances to the grueling Ironman and beyond. Use this information to choose the right race format for your experience level and training capacity.
What Is A Triathlon?
A triathlon is a multisport race consisting of three continuous disciplines: swimming, cycling, and running, completed in that specific order. The clock starts at the beginning of the swim and runs continuously until the finish line of the run, including transitions between activities.
Triathlon Order and Format
The standard triathlon order is always:
- Swim - Typically in open water (lake, ocean, or river) or occasionally in a pool
- Bike - Road cycling on paved surfaces (except in off-road triathlons)
- Run - Road or trail running to the finish line
Between each discipline are transitions (T1 between swim and bike, T2 between bike and run) where athletes change gear and equipment.
How Long Is A Triathlon?
The question "how far is a triathlon" depends entirely on the race format. Triathlon distances in miles range from very short (Super Sprint) to extremely long (Ironman and beyond):
- Super Sprint: 0.25mi swim + 6.2mi bike + 1.55mi run
- Sprint: 0.47mi swim + 12.4mi bike + 3.1mi run
- Olympic/Standard: 0.93mi swim + 24.9mi bike + 6.2mi run
- Half Ironman/70.3: 1.2mi swim + 56mi bike + 13.1mi run
- Full Ironman/140.6: 2.4mi swim + 112mi bike + 26.2mi run
How To Train For A Triathlon
Effective triathlon training requires balancing all three disciplines, plus transitions practice and appropriate recovery. A good triathlon training plan will include:
- Swim sessions focusing on technique and endurance
- Bike workouts building cycling strength and efficiency
- Run training with emphasis on maintaining form after cycling
- Brick workouts (bike-to-run sessions) to practice transitions
- Strength and flexibility training to prevent injuries
- Proper recovery and nutrition strategies
How long a sprint triathlon training plan or ironman training program should be depends on your current fitness level, experience, and the race distance. Beginners typically need 8-12 weeks for a sprint triathlon, while ironman training might require 6+ months of dedicated preparation.

Which Triathlon Distance is Right for You?
Choosing the right triathlon distance depends on your fitness level, experience, available training time, and goals. Here are some recommendations:
- First-time triathletes: Start with a Super Sprint or Sprint distance to build confidence
- Limited training time (under 5 hours/week): Focus on Sprint distance races
- Moderate training time (7-10 hours/week): Olympic/Standard distance is achievable
- Significant training time (10+ hours/week): Consider Half Ironman/70.3 events
- Experienced triathletes with 15+ hours/week to train: Full Ironman distance can be a goal
Remember that enjoyment should be a key factor in your decision. Many triathletes find their preferred distance based on their natural strengths and the type of training they enjoy most.
