Finding Race Intensity
Race intensities are estimates based on critical swim speed. Fractional utilization is individual, so we recommend you trial these intensities in training before race day. Try a longer session like 10 x 200 m (15 sec recovery) at the pace suggested here, and see if the intensity matches the correct RPE for 70.3.
| Name | Pace (mins/100m) | RPE* |
|---|---|---|
| <5 hours | - | 7.5 |
| 5-6 hours | - | 6.5 |
| 6-8 hours | - | 6 |
