Split planner
A goal time as the number you need to see at each marker — even, a negative split, or the fade you would rather plan than discover.
Three ways to run the same time
Even
The same pace from the gun to the line.
Negative split
Start controlled, finish faster. How most good races are run.
Fade
Bank time early and give it back. Plan for it if it is the plan.
Pace moves in a straight line from the first kilometre to the last, so a 2% negative split really is a second half two per cent quicker than the first rather than a sprint at the end. Whichever shape you pick, the finish time is the one you asked for.
Not sure what to aim for? The race time predictor turns a result you have already run into a goal that is plausible.
