You're really proving you deserve your name.
No one is saying foot races encompass the entire spectrum of athletic skills (dexterity, power, agility, strength, wits etc.) That doesn't make it easy. By your logic, you could strip everything down to its fundamental elements and say it's easy because it excludes certain things because, quite simply, no athletic event can incorporate every single element of athleticism.
