How much you ran and trained each week. Distance and cross-training come from Garmin; Stryd's Running Stress Score (RSS) weighs each run by its power.
Critical Power (CP) is the highest power you could hold for roughly 40–60 minutes. Efficiency is how much power you produce per heartbeat on steady runs — up means fitter.
Garmin's overnight and all-day signals, as 7-day averages. A rising resting heart rate, falling Body Battery and short sleep together usually mean fatigue. Dashed lines mark marathon days.
Every marathon in your Stryd history. %CP is race power as a share of your CP on the day; around 80–85% is typical for a marathon.
Each bar is one lap (you pressed lap at each mile marker). Power drifted down steadily through the first half and fell sharply after about 32 km, when walk breaks began.
