Units
LeCoach currently uses metric units everywhere: kilometers, min/km paces, kilograms and meters. There is no imperial (miles / min/mile / lbs) display setting yet — apologies to our imperial-minded athletes. It's a known request: upvote it on our feature board to help prioritize it.
Note that your devices still show *their* configured units while riding — the workout targets themselves are percentages, which are unit-free. Chat is flexible too: ask your coach in miles and it will happily answer in miles.
Timezone
Set your timezone in Settings → Profile → Timezone (it can also sync from Intervals.icu). Your timezone anchors your training days and determines when your morning briefing and other notifications arrive. Traveling? Update it and your mornings follow you.
