How this is measured

Not a thermometer at the finish line — few races record one. These are modelled reconstructions for the race's city and date, averaged over the race morning, roughly 4am to noon. They are humidity-aware: a muggy 24°C morning counts as hotter than a dry one, because sweat evaporates less. They are also shade estimates, with no direct-sun component, so they read conservative rather than inflated. Full method.
