Running Pace Guide

What is a good running pace for beginners?

A comfortable jogging pace for beginners is usually 7–9 min/km. You should be able to hold a conversation. As fitness improves over weeks, pace naturally improves.

What pace should I target for a sub-4 hour marathon?

To finish a marathon in under 4 hours, you need to maintain approximately 5:41 min/km (about 9:09 min/mile) consistently across all 42.2 km.

How do I improve my running pace?

Consistent training is the key. Mix easy runs (80% of your runs) with speed work — intervals, tempo runs, and hill repeats. Increase weekly mileage by no more than 10% per week to avoid injury.
