Frequently Asked Questions
Swimming
Is open-water swimming harder than pool swimming? expand_more
Yes. Open water adds waves, sighting, temperature variations, and no lane lines. Practicing in lakes or the ocean helps build confidence for triathlon races.
Do I need a wetsuit for a triathlon? expand_more
Wetsuits increase buoyancy and speed and keep you warm. They are required in colder races and optional in warmer conditions.
How often should triathletes swim per week? expand_more
Beginners: 2× per week Intermediate: 3× per week Advanced/Ironman: 3–4× per week depending on race goals.
Cycling
Do I need a special triathlon bike? expand_more
No. A regular road bike is perfect for most athletes. Triathlon/TT bikes offer aero advantages but are not required for training or racing.
How often should triathletes cycle per week? expand_more
Most triathletes ride 2–4 times per week. Long rides improve endurance, while interval sessions build power and speed.
What is the best way to improve bike performance? expand_more
Combine long aerobic rides, hill repeats, tempo sessions, and strength training. Consistent cadence and proper bike fit also boost performance.
Running
Why does running after cycling feel so hard? expand_more
Your legs are fatigued and your neuromuscular system must adjust. Brick workouts (bike → run) help your body adapt and improve transition performance.
How often should triathletes run per week? expand_more
Beginners: 2–3× per week Intermediate: 3–4× Advanced/Ironman: 4–5× depending on injury history and volume tolerance.
How do I improve my running form for triathlon? expand_more
Focus on cadence (170–180 steps/min), upright posture, forward lean, and controlled breathing. Strength training for hips and core also helps.
