Prefer to watch? A coach reads one athlete’s week, a run and a ride, the way she would in a review: the pills, the boxes, the zones, the athlete’s own feel, and whether the engine is getting better.

What does the chart on a finished workout show?

  • Coach
  • Athlete

Open a finished workout from the schedule, your dashboard or a notification and, when the watch recorded it, the detail page carries a chart. The blue line is the athlete’s pace for a run (power for a bike, see How does the chart differ for a bike workout?), read from the watch file.

The workout chart on a desktop: a Time / Distance toggle, GAP and Workout Target checkboxes and an Overlay select above a pace line with grey target boxes, and the caption Workout Target: Executed steps below.
A hill-repeat run on a desktop, with the defaults: time axis, Workout Target on, and the caption that names where the targets came from.

The ? icon at the very end of the control row opens this page.

The chart's control row with the help icon highlighted at its far right end, after the expand icon.
The ? icon, last in the control row, opens Reading a workout in a new tab.
  • Time or Distance along the bottom. Time is the default (moving time, so watch pauses take no width); Distance stretches the same workout over the miles or kilometres run. The axis ends where the data ends, not at the next round number.
  • The legend above the plot names the series, and any overlay you add joins it.
  • The scale on the left fits the real effort. A GPS spike or a few seconds at a standstill do not stretch the axis, so the intervals stay readable; the targets are always kept in view.
The same run with the Distance axis selected; the bottom axis reads in miles and the target boxes span the distance each step covered.
Distance axis: the same steps, placed where they fell along the run.

What are the grey shapes under the line?

  • Coach
  • Athlete

When the workout was assigned with targets, every step with a pace or power target draws two grey shapes:

Close-up of four hill repeats: for each one a dark grey box spans the target pace range near the top of the plot and a lighter grey skyline fills the plot from the bottom up to the slow edge of the target; recovery steps between them have a blue tint and dashed dividers.
Repeats 3 to 6. The darker box is the target range; the lighter skyline below it is everything slower than the target.
  • The box spans the target range for that step (a thin band when the target is a single value). The line sitting inside the box means the step was run on target.
  • The skyline fills the plot from the bottom up to the slow edge of the target. Where the line is above the skyline, the athlete was faster than the target asked for; inside it, slower.
  • The tint behind each step is its intensity: warm-up, cool-down and recovery steps are blue, active and interval steps amber, rest steps have none. Dashed dividers mark where one step ended and the next began.

Hiding the targets

Untick Workout Target (on a phone it is in the gear menu, see Where are the chart options on my phone?) to see the line on its own. The boxes and skyline go; the tint and dividers stay, so you can still tell the steps apart.

The chart with the Workout Target checkbox unticked and highlighted: the pace line over tinted steps with dashed dividers, with no boxes or skyline.
Workout Target off: the same run without the boxes.

Where the targets come from

The caption under the chart says which targets the boxes show:

  • Workout Target: Executed steps - the watch recorded the structured workout, so each box sits exactly where that step was run, pauses excluded. A session cut short shows only the repeats that happened.
  • Workout Target: Planned - the watch did not record the steps (a free run matched to the assignment, or an older watch), so the plan is replayed as written from the start.
  • Workout Target: Targets from the watch (plan changed since) - the workout was edited after it was sent to the watch, so the boxes show the targets the watch actually had.

Targets are the athlete’s own: a step written as a percentage of threshold pace or FTP becomes that athlete’s pace or watts. See Zones and benchmarks.

What does the card show when I hover or tap the chart?

  • Coach
  • Athlete

Move the mouse over the plot (on a phone, touch and hold a point) and one card follows the cursor:

The chart with the cursor inside repeat 7; a dark card reads 22:16 · Repeat 7 of 12 · Active, then Current: 7:58 /mi, Target: 5:34-6:03 /mi and Lap average: 7:32 /mi.
The card inside repeat 7: the moment, the step, and three paces.
  • The title is the moment (time or distance, matching the axis) and the step it falls in, for example 22:16 · Repeat 7 of 12 · Active.
  • Current is the value at that moment.
  • Target is the step’s target range. It appears only inside a step with a target, and only while Workout Target is on.
  • Lap average is how the athlete actually ran that whole step, so you can compare it with the target without reading the line.
  • An overlay series, if you added one, follows as its own row.

What is the pause icon on the chart?

  • Coach
  • Athlete

A grey pause icon (two bars in a circle) near the top of the plot marks where the watch stopped - the athlete pressed pause, or auto-pause kicked in at a road crossing.

The chart with the pause icon highlighted near the top of the first long step at about 6:10, the cursor just after it on the pace line and the tooltip card for the neighbouring sample at 6:16.
The pause icon sits at the moment the watch stopped; the card shown is for the sample just after it. The time axis is moving time, so the pause itself takes no width.

The time axis counts moving time, so a pause does not stretch the chart; the line simply continues from where the watch resumed. The card on the sample where the stop sits adds a Paused line with the length of the stop, for example Paused 0:22. On the Distance axis the icon is not drawn - nothing was covered while stopped.

What are GAP and Overlay?

  • Coach
  • Athlete

Both live in the control row above the chart (in the gear menu on a phone).

The chart with GAP ticked and Heart Rate chosen as the overlay: the primary line is labelled GAP and a second, red heart-rate line is plotted against a bpm axis on the right.
GAP on, Heart Rate overlaid on its own axis.
  • GAP (grade-adjusted pace) is offered for runs with elevation data. Ticking it swaps the pace line for the pace the same effort would have produced on flat ground, so a hill repeat run uphill at 7:40 can read as a 6:30 effort. The target boxes stay where they are; compare GAP with the target on a hilly course.
  • Overlay adds a second series on its own axis on the right: Heart Rate, Elevation or Cadence when the watch recorded them, and Speed on a power chart. Choose None to take it away. The overlay joins the legend and the tooltip card.

Where are the chart options on my phone?

  • Coach
  • Athlete

On a phone the chart runs edge to edge and the control row is one line: the Time / Distance toggle stays visible, and the rest moves behind the gear icon.

The workout chart on a phone: the Time / Distance toggle, the expand icon, a gear icon and a help icon in one row above a shorter chart.
The chart on an iPhone in portrait.
The phone chart with the gear icon highlighted and its menu open, listing GAP, Workout Target, and under Overlay the choices None and Heart Rate.
The gear menu holds GAP, Workout Target and Overlay. It stays open while you change several.
  • Tap the gear for GAP, Workout Target and Overlay. The menu stays open while you flip them, so you can switch two things in one go; tap outside to close it.
  • The gear is hidden when there is nothing to choose - no elevation for GAP, no targets, and no overlay series in the file.
  • The rotated axis titles are not drawn on a phone; the legend above the plot names the series instead, which gives the plot the extra width.
  • To see the card, touch and hold a point on the chart. For a bigger chart see How do I make the chart bigger?.

How does the chart differ for a bike workout?

  • Coach
  • Athlete

A ride recorded with a power meter or a smart trainer is charted on a power axis in watts.

A cycling workout chart: a power line in watts with grey target boxes for each interval, the legend reading Power (W).
A trainer ride: watt targets, each step a box on the power axis.
  • The target boxes are watt ranges. A step written as a percentage of FTP is scaled to the athlete’s own FTP from their benchmarks, so two athletes riding the same workout see different boxes. See Zones and benchmarks.
  • Speed is offered as an overlay on a power chart; GAP is not, since it is a running measure.
  • A ride without power data falls back to a speed chart; a power-targeted workout ridden without a power meter shows no boxes, because watts cannot be drawn on a speed axis.

How do I make the chart bigger?

The expand icon (four corners) in the chart’s control row expands the chart.

The expand icon sits at the right end of the control row.

Tap it and the same chart - its control row, legend, plot and caption - fills the screen above the app bar. Nothing is redrawn, so the axis you chose, GAP, Workout Target and the overlay are exactly as they were, and the card still follows your finger.

The expanded chart on a phone held in landscape: the control row along the top, the pace line and target boxes filling the width of the screen, and the collapse icon in place of the expand icon.
