Skeleton Calories Calculator: 175 lb, 45 Min, 357.2 kcal
On the defaults — 175 lb, 45 minutes at MET 6 — skeleton burns 357.2 kcal, 476.27 kcal an hour, 7.94 kcal a minute. This is the skeleton calories tool: weight in kilograms times the MET value is the hourly burn, and the hourly burn times the minutes on the run is the total — a run guessed from the clock alone tells you nothing until the weight and the effort behind it are known.
What does 357.2 kcal mean?
It means a 175 lb rider in a 45-minute skeleton session at MET 6 burns three hundred and fifty-seven kilocalories, which is 476.27 kcal an hour and 7.94 kcal a minute. The weight sets how much body the run has to move, the MET value sets how hard the moving is, and the minutes set how long it goes on: one more minute adds 7.94 kcal at the default pace, and a harder session adds kilocalories to every minute without the clock moving at all. The only judgement is the MET value itself — a gentle ride down the track and a full training session are not the same outing, and the effort actually spent is the only honest source for it.

Three things to check before you trust the number
First, check the minutes honestly: 45 minutes must be minutes actually skeleton racing, not minutes spent queuing for the sled, watching other runs, or warming up inside — a minute counted that was spent in the queue adds 7.94 kcal that was never burned. Second, check the weight against the rider: 175 lb must be the rider actually on the sled, not an average across a mixed crew of adults and juniors — weight scales every minute, so mixing riders breaks the total. Third, check the MET value against the session: MET 6 must be the session actually raced, not a gentle ride scored as a workout — the sprint start, hard steering, and bracing through corners all lift the effort, while lying still as a passenger lowers it.
Worked example
175 lb, 45 minutes, MET 6. Kilograms: 175 × 0.45359237 = 79.38 kg. Per hour: 6 × 79.38 = 476.27 kcal. Total: 476.27 × 45 ÷ 60 = 357.2 kcal. Per minute: 357.2 ÷ 45 = 7.94 kcal. In practice that means three quarters of an hour of skeleton burns about as much as a brisk half-hour walk, and the 476.27 kcal per-hour figure is the one to set against other winter sports, since one hour is the unit every activity shares.
Every branch, checked
At 30 minutes instead of 45, the total falls to 238.14 kcal — 476.27 kcal an hour, 7.94 kcal a minute. At 60 minutes instead of 45, the total rises to 476.27 kcal — 476.27 kcal an hour, 7.94 kcal a minute. At MET 8 instead of 6, the total rises to 476.27 kcal — 635.03 kcal an hour, 10.58 kcal a minute. At 200 lb instead of 175, the total rises to 408.23 kcal — 90.72 kg, 544.31 kcal an hour, 9.07 kcal a minute.
The reverses, worked backwards
The minutes behind 357.2 kcal are 45: at 30 minutes the total is 238.14 kcal; at 60 minutes it is 476.27 kcal. The MET behind 357.2 kcal is 6: at MET 5 the total is 297.67 kcal; at MET 8 it is 476.27 kcal — the MET value never touches the minutes, only how hard each minute is.
What the defaults assume
The defaults assume 175 lb, 45 minutes, and MET 6, for one rider in a proper session. They do not assume track length, ice conditions, temperature, clothing weight, or waiting time between runs — so treat 357.2 kcal as the planning burn for 45 minutes at MET 6, and check it against the session actually raced before logging it as exact.
Who uses this
- A rider planning a track day: the 357.2 kcal is the figure to set against lunch afterwards.
- Someone comparing winter sports: the per-hour figure compares skeleton fairly with luge and bobsledding.
- A person tracking daily activity: the total adds the session to the day exactly.
- A coach planning training time: the per-minute figure prices a track session in activity terms.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the minutes actually raced, the true weight, and the true MET value for that session. Real sessions vary with track, ice, and how much sprinting the run layout forces — so treat 357.2 kcal as the planning burn for 175 lb, 45 minutes at MET 6, and check it against the session before logging it as exact.

Frequently asked questions
How many calories does skeleton burn?
357.2 kcal on the defaults: 175 lb, 45 minutes at MET 6 — 476.27 kcal an hour.
How many calories does skeleton burn per hour?
476.27 kcal an hour on the defaults: MET 6 × 79.38 kg.
How many calories does skeleton burn per minute?
7.94 kcal a minute on the defaults: 357.2 kcal ÷ 45 minutes.
Why does the MET value matter so much?
Because it scales every minute: at MET 8 the same 45 minutes burn 476.27 kcal, while at MET 5 they burn 297.67 kcal.
How do I burn more while skeleton racing?
Race longer or harder: 60 minutes burns 476.27 kcal, and a MET 8 session burns 476.27 kcal in 45 minutes.
Does queuing for the sled count?
Only if it is part of the session: sprinting and bracing are real effort, but minutes spent standing in the queue are not racing minutes.
