Frequently Asked Questions

What is a good running pace?+
It depends on fitness level. A recreational runner typically runs 10–12 min/mile (6:20–7:30 min/km). A good amateur pace is 8–10 min/mile. Competitive amateur runners aim for 6–8 min/mile. Elite marathon runners run under 5 min/mile (3:06 min/km). Walking pace is typically 15–20 min/mile. Any consistent movement is beneficial regardless of speed.
How do I calculate pace from time and distance?+
Pace = Total Time ÷ Distance. For example: running 5 miles in 45 minutes = 45 ÷ 5 = 9 min/mile. To convert pace to speed in mph: Speed = 60 ÷ pace (in minutes). A 9 min/mile pace = 60 ÷ 9 ≈ 6.67 mph. To find finish time: Time = Pace × Distance, so 9 min/mile × 13.1 miles = 117.9 minutes = 1h 57m 54s.
