Enter your race distance and goal time to see pace estimates and race planning data.

Results will include required pace, speed, and expected split times.

How Race Time & Pace Estimation Works

Required Pace Calculation

Pace per Mile: Goal time ÷ Distance in miles = Required pace per mile
Pace per Kilometer: Goal time ÷ Distance in kilometers = Required pace per kilometer

Average Speed Estimation

Speed (mph): (Distance in miles ÷ Goal time in hours)
Speed (kph): (Distance in kilometers ÷ Goal time in hours)

Split Time Projections

Split times are projected proportionally: (Split distance ÷ Total distance) × Goal time = Expected split time
These assume even pacing and help you plan race strategy and checkpoints.

Race Planning Applications

Use required pace for tempo runs and race-pace training sessions.
Split times help you stay on track during the race and adjust strategy if needed.
Export data to track goal progression and share with coaches or training partners.

About This Race Planning Tool

The Race Time & Pace Estimator helps runners set realistic goals and plan effective training strategies. Whether you're aiming for a personal best in a 5K or training for your first marathon, this tool provides the precise pace calculations needed to achieve your race goals.

The CSV export feature enables detailed race planning and training log management. Track your goal progression over time, share race strategies with coaches, or analyze different time scenarios for optimal race day preparation.

All calculations happen locally in your browser - no race goals or personal data is sent to servers, ensuring complete privacy of your training and racing information.

Frequently Asked Questions (FAQ)

How does the race time and pace estimator work?
Enter your goal race distance and target finish time, then click estimate. The tool calculates your required pace per mile and kilometer, average speed, and split times for common race distances to help you plan your race strategy.
What's the difference between race time estimation and pace calculation?
Race time estimation helps you predict when you'll finish based on your planned pace, while pace calculation shows what pace you need to achieve a specific finish time. This tool does both - enter your goal time to get the required pace.
How do I use this for race planning and training?
Set your race goal time (like sub-4:00 marathon), and the estimator shows your target pace. Use this pace for tempo runs and race-pace training sessions to build familiarity with your goal speed and race day strategy.
Can I export my race planning data?
Yes! Click "Export to CSV" to download all your race time estimates and pace calculations. Perfect for training logs, sharing with coaches, or tracking your goal progression over time.
What are split times and how do they help race planning?
Split times show your expected finish time for shorter distances within your race. For example, if you're planning a marathon, you can see what your 10K, half marathon splits should be to stay on track for your goal time.
How accurate are these race time estimates?
The estimates assume even pacing throughout the race. Actual race times may vary based on course difficulty, weather, fitness level, and race strategy. Use these as planning guidelines and adjust based on your training and experience.
Is my race planning data processed securely?
Yes, all calculations happen in your browser. No race goals, times, or personal data is sent to any server - everything is processed locally for complete privacy.
