Training load and form

Where training load from power, pace, heart rate or RPE comes from, which athlete thresholds it needs, and how to read the load chart and the form chart.

For coaches and athletesUpdated:

Training load turns the duration and intensity of a workout into one number, so sessions from different sports add up to a week and weeks line up into a form chart. There is one scale: 100 points is an hour at threshold.

OverviewStatistics

What the load is based on

Every activity gets one number, from the most precise data it has, in this order:

  1. Load from power: a ride with a power meter and an FTP set. If the watch already calculated load from power, the app uses its number.
  2. Load from pace: a GPS run when the athlete has a threshold pace. Uphills and downhills are corrected for gradient.
  3. Load from heart rate: any sport with a heart rate monitor, once maximum heart rate is set.
  4. Load from RPE: the 1-10 effort rating times the duration, when there is no measurement at all.

Power and pace are measured against a threshold; heart rate and RPE are estimates, so in the calendar their result carries a tilde, for example ~28. A workout with none of this data gets no load at all, rather than a zero that would drag the week down. On a treadmill, heart rate takes priority over pace.

  1. Check the method in the activity panel

    Click an activity in the calendar. The row label in the metrics tells you which method produced the number, for example Load from pace.

    Run metrics: pace, distance, duration, average heart rate and the highlighted Load from pace row
  2. Set the athlete's thresholds

    Without FTP, a ride with a power meter falls back to heart rate, and without maximum heart rate it falls back to the effort rating. The coach sets the thresholds in the athlete overview, in the Training Zones section. The athlete sets them in Profile, on the Athlete Data tab, in the Training Settings card.

  3. Compare weeks

    The weekly total sits above the calendar; hover over it to see the split by method.

    In statistics, on the Training tab, the Training Load chart puts weeks side by side, split by sport, and the line under the title says how many activities each method covered and how many have no load.

  4. Follow form

    The Overview tab has the Form chart. Grey bars are daily load, the Fitness line is the effect of roughly six weeks of training, and Freshness is the gap between that and the fatigue of the last week: below zero the athlete is building up fatigue, above zero they are rested.
