The Ivan Scale Of Perceived Suffering
This scale is a result of many runs and races where mental toughness was the greatest challenge. Scales of perceived exertion or perceived effort can be useful, but these do not apply well when the limiting factor is not how intensely you are exercising. This scale of is based on how much perceived suffering is experienced. On a 100 mile race, it is possible to have a low perceived effort, but undergo immense suffering.
1 Ivan Castro
I used the units of 'Ivan' after my one of my running heroes Ivan Castro. On many runs I have reached the point where I seriously consider quitting. At these times I often think of Ivan, his determination and spirit. Ivan is not superhuman; he is an ordinary man who refuses to quit.
The indications are suggested guidelines, and a workout meeting one criteria would use that level, e.g. nearly crying would define a run as 7 on the Ivan scale.
