Math in the runner's dimension

I realized something Saturday on my long run. Once you pass the 16 mile mark, you enter another dimension and all laws of mathematics go out the window. For example, in our everyday dimension, 18 miles is simply 2 miles more than 16. Not so in the runner's dimension. Therefore, I came up with an equation for how mathematics rules apply in the runner's dimension:

d^LSD= d₀ + е^(d>16)

where d^LSD is the distance of a long slow distance run
and d₀ is the distance of the run up to 16 miles
and e is the Euler's constant which is approx equal to 2.7182
and d>16 is the distance your run is greater than 16

for example, an 18 mile run is actually 23.38 miles.
A 20 mile run is actually 70.59 miles.
A marathon? 22,052 miles.

Things are suddenly so much clearer.
