Estimate calories burned during hill sprints from your weight and total sprint time, or from sprint count and seconds per sprint.
Hill Sprints Calories Burned Formula
For hard hill sprint work, calories burned scale directly with body weight and sprint time.
C = Wlb × M × 0.1193
If you track your workout by reps, first convert your intervals into sprint minutes.
M = (R × S) / (60)
C = Wlb × ((R × S) / (60)) × 0.1193
Variable Meanings
- C = calories burned (kcal)
- Wlb = body weight in pounds
- M = total hill sprint minutes
- R = number of sprints
- S = seconds per sprint
How to Use the Calculator
- Use Basic if you already know your total sprint minutes.
- Use Advanced if you track hill sprints by reps and seconds per rep.
- Enter your body weight, calculate, and read the calories burned.
Calories Burned Per Minute
| Weight | Calories per Minute |
|---|---|
| 100 lb | 11.9 kcal |
| 120 lb | 14.3 kcal |
| 150 lb | 17.9 kcal |
| 180 lb | 21.5 kcal |
| 200 lb | 23.9 kcal |
Quick Reference Table
| Weight | 5 Sprint Min | 10 Sprint Min | 15 Sprint Min |
|---|---|---|---|
| 120 lb | 71.6 kcal | 143.2 kcal | 214.7 kcal |
| 150 lb | 89.5 kcal | 179.0 kcal | 268.4 kcal |
| 180 lb | 107.4 kcal | 214.7 kcal | 322.1 kcal |
Interval Examples
At 150 lb, short uphill intervals add up quickly:
| Workout | Total Sprint Time | Calories Burned |
|---|---|---|
| 8 × 15 sec | 2.0 min | 35.8 kcal |
| 10 × 20 sec | 3.33 min | 59.7 kcal |
| 12 × 30 sec | 6.0 min | 107.4 kcal |
| 15 × 20 sec | 5.0 min | 89.5 kcal |
Example
A 150 lb runner doing 10 hill sprints at 20 seconds each logs 3.33 sprint minutes.
M = (10 × 20) / (60) = 3.33
C = 150 × 3.33 × 0.1193 ≈ 59.7
What Raises the Total
- More sprint minutes: doubling sprint time doubles calories burned.
- Higher body weight: heavier runners burn more calories per minute at the same workload.
- Longer reps: 30-second sprints burn twice as much as 15-second sprints when rep count stays the same.
- More reps: extra intervals increase total sprint minutes and total calories.
