Although the intensity of a maximal 4-minute effort is far higher than ultra-distance power, it still has a direct relationship with performance. This is because the maximal power attained over 4 minutes is an excellent indicator of your maximal aerobic engine.

This session comes with a twist! We're also interested in your best 4-minute power under fatigue. This gives us an idea of both aerobic capacity and your overall endurance. Both critical for ultra-distance triathlon of course!
