Race time predictor
The Time machine.
The Driftline time machine accurately predicts potential race times for everyone regardless of age, gender, or fitness level. The Indurance app does this automatically for the user - you can also use it manually by adjusting only two parameters: max speed, and endurance. Click to fix one known race time for yourself and continue to move the sliders until you find a good fit.
Please bear in mind that endurance runners tend to overestimate their endurance when using the time machine. This is because their 5K and 10K personal best times are typically set when the runners are not in peak race condition and perhaps less motivated. Ideally, the best option is to perform an automatic race prediction with the Indurance app.
Exercise thresholds reflect the transitions between different types of muscle fibers during exercise. Use the sliders to see how endurance affects the alignment of exercise thresholds.

With Driftline analytics all exercise thresholds, including the lactate threshold (critical threshold), can be easily measured. Previously, this could only be measured by needles inserted directly into the body. NO MORE!
Driftline calculates optimal training paces and accurately identifies the ideal heart rate for each training session. If you know your maximum heart rate (HRmax), you can select it and use the sliders to estimate your ideal training paces and heart rates. For accurate HRmax and training paces you should use the Indurance app.
|Training paces||T||Speed |
|Endurance training pace||1.67||13.33||4:30||141|
|60 minute pace||1.83||14.17||4:13||150|
|Lactate training pace||2.00||15.00||3:59||159|
|30 minute pace||2.08||15.42||3:53||159|
The indicated heart rate is the ideal steady-state heart rate for heart rate based training. On a steady pace the heart rate will gradually drift upwards, so the pace should be gradually reduced to keep the heart rate steady. The ETP and the LTP training paces and heart rates, have been shown to be optimal for endurance training.
Your critical distance (CD) is the maximum distance you can run on your critical threshold pace (T2). The CD is strongly endurance related and ranges from less than 5 km up to about 40 km for world class distance runners.
You can easily slow down and run farther than your CD, but for maximum efficiency, your CD should match or surpass your chosen race distance. In fact, only the most elite marathon runners are maximally efficient for the marathon.
Move the sliders to see how the speed thresholds are affected by endurance and max speed.
The Runscore is a universal fitness metric adjusted for age, gender, and distance. It is based on the World Athletics scoring tables and gives a fair fitness score on a scale of 0 - 10. World-class runners at any distance may, however, tip the scale and a world-record performance may produce a Runscore of around 11.
