What should today look like?
Before you lace up: the session, what to expect, and how you come in.
Today's runThe session from your plan, its limits, and one tap to send it to your watch. Morning readThe heart rate your own recent runs expect at today's pace, and how often that has held. Step up in distanceA run much longer than your longest of the last 30 days is pointed out before you run it. Overnight noticeSaid only when your mornings are off two days in a row. It never tells you to rest. Recovery after a hard sessionOne cell per night until your mornings are back to your usual. Check-ins, effort and fuelOne tap for sore legs, stress, travel or a niggle, and how hard the run felt. Back after a breakYour first runs back, set against the weeks before the break. Your week by intensityPlanned runs as outlines, km run split into easy, moderate and hard. Widgets and race-day Live ActivityYour next session and your week on the Lock Screen and Home Screen. Plan BCan't run today? The best day this week to move the session to, and what it does to the week.
How did this run go?
Every run read the way it was meant, in plain words.
Coach's readA run summed up in one sentence, then each part in plain words with your own numbers. Intervals, rep by repEvery rep against its target: on target, slightly off or clearly off, faster or slower. Did easy stay easy?How much of an easy run went above your easy-run ceiling. Heart-rate driftDid the same pace cost more heart rate in the second half than in the first? Where drift startsOn long runs and races, the km after which each heartbeat bought less speed. A year apartThe same kind of run, a year earlier, side by side. Fuel on a runCarbohydrate and fat used on long runs, as a likely range, never a 'fuel left' number. Session as writtenPaste your coach's session onto a run and it is read rep by rep. Every run gets a typeEasy, long, threshold, intervals or race. When Cursans is not sure, it asks you once in Today's One question card. Your answer always wins.

One honest trend per kind of run, and what moves it.
Progress by workout typeEasy, long, threshold and intervals each tracked against their own kind. Improving only when it is realGreen only when the change is bigger than your normal ups and downs. What affects youHeat, hills, wind, time of day, sleep, HRV and check-ins, each tested on your own runs. Chart without the heatA switch that redraws the trend without the weather. The verdict still reads your runs as measured. What holds your late driftOn runs of an hour or more: what goes with your heart rate creeping up late.
