Frequently Asked Questions
How fast do I need to run a 5K in 20 minutes?
Average pace 4:00 /km (6:26 /mi), 15.00 km/h.
Should I run even splits?
Even effort is the most economical, but the first 10–15% is usually crowded. Start 5–10 s/km slower and settle into target pace.
My GPS shows extra distance
Courses usually measure a few hundred metres long on GPS. Run slightly faster than target by feel, or lap manually at the markers.
