Yeah your commute energy burn does look high in comparison to your 10k effort but the half marathon seems about right and i suppose it doesn't really matter unless your dieting and all your efforts are under 90 mins so can rely on stored glycogen and don't have to worry about fueling during exercise.

Cheers! They seem quick but need to break em in as they’re a bit solid right now. Recorded with a Polar M430. It’s got my age, height and weight in but could be wrong.
When I ride the 18 miles to work at low effort it registers it at 700ish calories which seems high, and half marathons are usually around 1300.
