Reading the pacing display
What the rabbit, target speed, and delta numbers mean during a run.
The pacing display tells you, at any moment, how to drive to hit your target time. It does this by simulating a virtual car — the rabbit — that drives the course at a perfectly even pace, and showing you where you are relative to it.
The rabbit
The rabbit is a virtual car traveling along the recorded course at the speed required to finish at your target time. If your target is 100 mph average over a 60-mile course, the rabbit drives at 100 mph from start to finish.
Delta
Delta is the gap between you and the rabbit, in seconds. Positive means you're ahead. Negative means you're behind. The number updates roughly 10 times a second.
Target speed
Target speed is the speed you'd need to hold from now to the finish to match the rabbit. If you've banked 5 seconds, target speed drops below your average target. If you're behind, target speed rises. It's a real-time correction — drive to the target speed and you'll catch the rabbit by the finish.
Color cues
Green = on pace or slightly ahead. Yellow = behind by a small margin. Red = significantly behind or trending wrong direction. The thresholds are conservative — green doesn't mean you can relax, it means you're hitting your number.
