Weather on your runs and plan

Runsei records the conditions you actually ran in (temperature, wind, humidity) on each run, and shows the forecast for your planned sessions around your usual training time. This is context, not just decoration: heat and wind cost pace and raise heart rate, so the coach factors them into how it reads a run — a high heart rate on a hot afternoon is a different story than on a cool morning, and it won't mistake weather for a fitness problem.
