Running

If you go to the route of carrying all your water, you might try running 6 miles with 3 liters first.

Sometimes I include gas stations or groceries on self-supported routes to refill. Sometimes I buy Gatorade or bring my own Tailwind mix and add it to water. Filtering from natural sources is also an option.

On some solo 50ks I’ve left the house with no water at all, only a plan for how I would acquire it periodically along the way. Without a hydration bladder a hydration belt has been sufficient to carry my gear.
