Read your splits at a glance

A splits table tells you what each kilometre cost. What it usually doesn’t tell you, without arithmetic, is the thing you actually want to know: did you hold it together, or did you give it away in the back half?

What you’re looking at

#

Each row is one split, with:

• Split — the kilometre or mile number
• Duration — time spent on it
• Pace — the number you came for
• Elevation — how much of the difference the hill explains
• Avg. Heart Rate — what it cost you

And across the bars, the dashed line: your average pace for the run. That one line is what makes the table readable at a glance:

• Bars growing past the line as you go down — negative split, you finished faster than you started.
• Bars pulling back from it — a fade.
• Bars sitting on it — an even run, which for a long run is usually the goal.

Tap any split

#

Tapping a row opens that single split — including Elevation Ascend and Elevation Descend separately, which is often the whole story behind a slow one. A kilometre 20 seconds off your average with 30 m of climb in it wasn’t a bad kilometre.

Pro adds two more numbers per split: Pace Stability Index and Efficiency Factor, for when you want to know whether a split was steady or just averaged out to the right pace.

5K splits, for longer runs

#

On anything long, kilometre splits become a wall of numbers. 5K splits roll them up into blocks big enough to show pacing strategy instead of noise — the natural unit for reading a half or a full marathon.

Worth knowing

#

• Segments is a different thing. If your watch recorded structured work — intervals, laps you pressed — those appear under Segments, matching the efforts you actually ran rather than arbitrary kilometre marks.
• A treadmill run still gets splits, worked out from your recorded distance.
• Don’t read a single split too hard. GPS settles over the first few hundred metres, so an opening kilometre is the least trustworthy one in the table.
