Question 1

How do I calculate my race pace?

Accepted Answer

Divide your goal finish time by the race distance. For example, a 4-hour marathon (42.195 km) means a pace of 5:41 per kilometer or 9:09 per mile. This calculator does the math for you and generates split tables.

Question 2

What is a negative split strategy?

Accepted Answer

A negative split means running the second half of your race faster than the first. Typically 5-10 seconds per km slower in the first half. It's the preferred strategy of elite runners because it prevents early fatigue and allows a strong finish.

Question 3

How accurate is a pace calculator for triathlon run legs?

Accepted Answer

Triathlon run paces are typically 10-30 seconds per km slower than standalone race paces due to fatigue from swimming and cycling. For sprint triathlons the difference is smaller, for Ironman it can be 30-60 seconds per km slower.

Know your splits before the start line
