Key Takeaways
- Kayaking MET values range from 3.5 (leisure paddling) to 12.5 (racing/competition) per the 2024 Compendium.[1]
- A 30-minute moderate kayaking session estimates approximately 184 kcal for a 70 kg person.[2]
- Water conditions (current, wind, chop) can increase the effort by 5–20% over calm flatwater.
- Whitewater kayaking demands significantly more effort than flatwater touring.
- These are informational estimates for personal journaling. Individual results vary.

| Activity | MET | 55 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|---|
| Leisure Paddling | 3.5 | 101 | 129 | 156 | 184 |
| Moderate Effort | 5 | 144 | 184 | 223 | 263 |
| Vigorous Effort | 7 | 202 | 257 | 312 | 368 |
| Whitewater (Moderate) | 5 | 144 | 184 | 223 | 263 |
| Whitewater (Vigorous) | 7 | 202 | 257 | 312 | 368 |
| Racing / Competition | 12.5 | 361 | 459 | 558 | 656 |
How the Estimate Works
The calculator uses the standard MET formula with an optional water condition modifier:[1]
Calories = (MET × Water_modifier × 3.5 × Wt_kg × Duration_min) ÷ 200
The water condition modifier reflects the additional paddling effort required to maintain pace against current, wind, or waves. Calm flatwater uses a 1.0× base; strong current/rough water applies a 1.2× multiplier.
