Overload Coach

Your thermometer wins - type it and it overrides everything below. Your Stryd's sensor comes next and does correct the score on its own, because it was on you for the whole run. ⚠️ It sits low, near hot tarmac, so if it looks too warm say what you measured.

Full sun is worth up to +15 °F (8 °C) of felt heat. ⚠️ The pre-filled figure is the strength of the beam - Open-Meteo's direct radiation as a share of 800 W/m², a clear sky at noon. What actually matters is how much of your route was in the open, which nothing models, so on a wooded or built-up run this will read high.

At the start of the run. Worth up to 6 bpm off your average HR inside three hours, nothing after - so it only changes anything if you ate within three hours. Blank is not zero.

Plain words are fine - the coach reads this, not a parser. Mention any pain, tightness or soreness: there is no separate injury form, so this is how it gets taken into account.

How hard it felt, regardless of pace. Worth entering when it disagrees with the numbers - that gap is the useful part.
