Question 1

Should I run even or negative splits?

Accepted Answer

Negative splits (faster second half) often feel strongest in races, but even pacing works well on flat courses.

Question 2

How does treadmill incline affect pace?

Accepted Answer

Equivalent effort pace is slower outdoors at 0% incline; 1% grade approximates outdoor energy cost on many treadmills.

Question 3

Do GPS watches match this calculator?

Accepted Answer

GPS drift and corner cutting cause small differences. Certified courses are measured along the shortest path.
