One of the greatest things about Spartan Races is that they have become a proving-ground for individuals looking to demonstrate their mental dominance over their physical limitations. What I mean is this:
Regardless of physical limitations (poor endurance, minimal strength, illness, disease, amputations, etc.) many people are completing Spartan Races to prove that they can. They are taking the limitations they have been given and excelling beyond them in amazing ways.
No matter what your excuse is, you are fully capable of finishing a Spartan Race as long as your mind is in it. For many of us, that means relying on teammates/friends/family to get us through. There is nothing wrong with helping each other achieve great things. That's how the world excels!
With all of this in mind, get yourself to the gym so I can yell at you. It'll make you better.
Love you bye!
