Weight, body and fitness
This section holds training calculations: running pace, average speed and projected times for common race distances.
They help plan training load but do not replace advice from a doctor or a coach.
Calculators in this section
Available now
- Running pace: distance and time converted to min/km, min/mile and km/h.
- Split times for 5K, 10K, the half marathon and the marathon.
Using the numbers
Base your pace on several sessions rather than one result: an average across runs describes your current form better and leads to a realistic race target.
Frequently asked questions
Are these useful for beginners?
Yes, the formulas are the same at any level.
Do they replace a running watch?
No. A watch measures pace as you run, while the calculator reports averages after the fact.
Is elevation included?
No, the result is an average pace without terrain or weather corrections.
