[This is the second part of an article using ultra marathon running to explain sizing. You can read the first part here: The Best Ultra Marathon Runner in the World Helps Explain Why Size Matters]
In the first installment, we established that smaller is better when it comes to estimation and sizing. We used Camille Herron (holder of nine ultra marathons distance world records) to illustrate that as volume increases velocity, confidence and predictability decrease. Below is a table with her personal bests (several of which are world records).
