Frequently asked questions
What is a good running pace for beginners?
For a new runner finishing a 5K, an 11:00–13:00 per mile pace (40–45 minute 5K) is solid. Trained recreational runners average 8:00–10:00 per mile (25–31 minute 5K). Sub-7:00 per mile is competitive amateur territory; sub-5:00 is elite. The right pace for you is one you can hold while breathing comfortably — being able to speak in short sentences is a good check.
How do I run negative splits?
Negative splits means running the second half of a race faster than the first. Start 5–10 seconds per mile slower than your target average pace; settle into goal pace by mile 2–3; accelerate the final third. This conserves glycogen, manages heat buildup, and is how nearly all marathon world records are set. Most amateur runners do the opposite (positive splits) and crash in the final miles.
What's the difference between pace and speed?
Pace is time per distance (e.g. 8:00 per mile). Speed is distance per time (e.g. 7.5 mph). Same idea, inverse units. Pace is standard among runners because it makes mental math easier on the run — '8:00 pace × 26.2 miles = 3:30:00' is straightforward. Most GPS watches show pace by default and speed only when selected.
