Triathlon race splits – Easy, Clear, Efficient
Triathlon isn’t just a sport; it’s a strategy game – a battle against time, terrain, and your own pacing. Whether you’re a beginner tackling your first sprint distance or an experienced athlete aiming to qualify for Kona, race planning is key. And that’s where this Triathlon Pace Calculator truly shines.
This calculator is more than just a digital stopwatch. It’s a smart, interactive tool built specifically for triathletes who want to understand, optimize, and predict their race splits with clarity. Swim, bike, run, and transition times are no longer vague guesses – this calculator brings everything into focus with one intuitive interface.
What makes this tool so powerful is its blend of simplicity and insight. You start by selecting your race distance – sprint, Olympic, 70.3, or full Ironman – and the calculator automatically loads the standard segment lengths. From there, you enter your target paces: swim pace in minutes per 100 m, bike speed in km/h, and run pace in minutes per kilometer. Everything updates live – your predicted splits, total time, and detailed pace variation tables.
New in the latest version:
- Mobile-optimized design for smooth use on any device – perfect for race morning planning.
- Intuitive pace/speed sliders for faster and easier target adjustments.
- Approximate calorie burn estimation (flat terrain) using the MET method for a well-trained athlete, based on your input weight (note: values are estimates, not lab-grade measurements).
- Clearer split display – splits are now listed vertically for easier reading, with pace variation tables placed right beside the input fields for each discipline.
Next to each discipline’s input fields, you’ll find a dynamic table showing how small changes in pace can influence your final time. The splits themselves are listed vertically for easy reading, making it simple to see your race plan at a glance. Wonder what shaving 5 seconds off your swim pace would do? It’s right there. Curious how much faster you’d finish if you ride 2 km/h harder? Already calculated. And with a single click (or a quick slider adjustment), you can set a new pace and see the results instantly.
This isn’t just a planner – it’s an insight engine. It helps you visualize the trade-offs between disciplines, balance your effort, and build a race plan that plays to your strengths. Push too hard in the swim and it might cost you on the run; underestimate your bike power and you’re leaving minutes on the table.
Everything is designed for clarity: a clean layout, responsive tables, real-time feedback, and pace formats that match what athletes actually use. No unnecessary units, no confusing abbreviations – just usable data and smart logic.
And because it’s entirely web-based, you can use it anywhere – at home, during training camps, or right before the race with your coffee in hand. It’s free, fast, and focused entirely on your needs as a triathlete. No account required, no distractions – just smart pacing insight at your fingertips.
The goal is simple: help you race smarter.
