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.
