Concept2 weight-adjusted time by body weight
Concept2's weight adjustment scales a time by a factor that depends on body weight. A 7:00 2000m at 75 kg has a factor of 0.897, which gives a weight-adjusted time of 6:16.7. This chart gives the factor and the adjusted time for body weights from 50 kg to 120 kg, in 5 kg steps.

| Body weight (kg) | Adjustment factor(exact) | Weight-adjusted 2000m time (from 7:00)(exact) |
|---|---|---|
| 50 kg | 0.820 | 5:44.4 |
| 55 kg | 0.837 | 5:51.5 |
| 60 kg | 0.854 | 5:58.7 |
| 65 kg | 0.869 | 6:05.0 |
| 70 kg | 0.883 | 6:10.9 |
| 75 kg | 0.897 | 6:16.7 |
| 80 kg | 0.910 | 6:22.2 |
| 85 kg | 0.922 | 6:27.2 |
| 90 kg | 0.934 | 6:32.3 |
| 95 kg | 0.945 | 6:36.9 |
| 100 kg | 0.956 | 6:41.5 |
| 105 kg | 0.966 | 6:45.7 |
| 110 kg | 0.976 | 6:49.9 |
| 115 kg | 0.986 | 6:54.1 |
| 120 kg | 0.995 | 6:57.9 |
- The weight-adjusted time is a comparison score for athletes of different sizes. It is not a pace to hold.
- The adjusted time is the 7:00 multiplied by the factor, so a heavier body gives a larger factor and a larger adjusted time.
Worked example
A 7:00 (420 seconds) 2000m at 75 kg has a factor of 0.897, so the weight-adjusted time is 6:16.7 (420 × 0.897). It is a comparison score, not a pace to hold.
How it is worked out
Concept2's weight adjustment multiplies a time by (body weight in lb ÷ 270)^0.222, to compare athletes of different sizes. It is a comparison score, not a pace to hold. Body weight in pounds is kg × 2.20462, and the factor is rounded to 3 decimals before it multiplies the time, as Concept2's calculator shows it.
