FAQ: Choosing Your First (or Next) Triathlon
Which triathlon distance is best for beginners?
The super sprint or sprint triathlon is ideal for most beginners. These races are shorter, more manageable and require less training time, making them the perfect way to experience all three disciplines without overwhelming your schedule.
Can I do a sprint triathlon without much swim experience?
Yes. Many sprint races are beginner-friendly and some offer pool swims instead of open water. Focus on getting comfortable in the water and building basic endurance. You don’t need perfect technique to finish.
How much time do I need to train for an Olympic triathlon?
Most athletes need 6 to 8 hours per week for Olympic-distance training. It’s a step up from sprint training and requires more consistency, especially in swimming and brick workouts.
When should I move up to a Half Ironman (70.3)?
Once you’ve built a solid base and are consistently training 8+ hours per week, you can begin preparing for a 70.3. Most athletes move up after completing a few sprint or Olympic races, but some go straight to long-course with the right plan and patience.
Is Ironman only for elite athletes?
Not at all. Ironman is about consistency and commitment, not elite speed. If you have the time, motivation and desire to train for 6+ months, it’s a life-changing challenge that’s accessible to everyday athletes.
