2026-05-27, 82kg, Apple Watch Ultra HR 155 avg. My reference for running 6mph is 810 kcal per hour. 27°C with a light breeze, 6:15am on the Tsuen Wan waterfront. I had to slow down for the last kilometre.
MET 9.4 is the approximate equivalent of my 82kg rate, not a separate measurement. My 82kg reference is 810 kcal/hour. At 70kg, that's about 691. At 98kg, about 968. The formula (minutes × MET × 3.5 × kg) / 200 is reference only. USDA FoodData is used for food cost, not exercise burn.
What could 30 min cover? About 405 kcal, close to McChicken (400 kcal). I'd treat that as a comparison, not a reason to earn a meal.
Running at 6 mph is a ten-minute mile, a steady pace many recreational runners use for a continuous route rather than short sprints. A track gives clean laps; a waterfront path offers room to settle into a rhythm without frequent crossings. Shoes, surface and the length of your stride can all change how the session feels.
Even an early run along the Tsuen Wan waterfront can feel sticky when Hong Kong's air is humid. Breathing becomes more deliberate than during a walk and conversation may come in fragments. Slow down when the pace stops feeling sustainable; a neat number on the watch is not worth forcing through fatigue.

Questions I get
How much does running 6mph burn in 30 minutes?
At my 82kg reference, 405 kcal. I'd adjust for your weight and effort above.
Would I burn the same amount at 70kg?
Probably not. The weight-scaled estimate is 691 kcal per hour, not a personal measurement.
Is the MET figure my actual Watch result?
No. MET 9.4 is an approximate equivalent of the 82kg rate, not another Watch measurement. I use 810 kcal/hour as the starting point.
