Equivalent Performances can be found under the Equivalent tab on V.O2 whether you’re an athlete or coach viewing an athlete’s calendar.
Keep in mind, these race performances are not predictions but rather physiological equivalent performances. Seeing your Equivalents can provide insights on how to adjust training to score better as the distance of the race gets longer or shorter.
You might find you have different VDOT scores depending on the distance and that might reflect your strength as a runner, your current training focus/volume and/or simply weather or course conditions for some races versus others.
For instance, if you’ve run a 22:38 5k but cannot achieve a 3:35:59 marathon performance that might be due to your training and/or course conditions. Obviously, the course and weather will have much more of an impact in a 3.5 hour race versus a 22-minute race. So if the weather isn’t ideal in a marathon it can significantly impact how well you run comparatively and your VDOT score will be lower than it should be.
In the case you have multiple race results and different VDOT scores always select the highest VDOT to determine your current fitness and training intensities. Ideally, you have good course conditions and weather to determine your VDOT, but if you’re running cross country it’s okay to use your race times for regular training sessions where you’ll face the same type of adversity in training.
