You can do this.

Hey, if I can do the 10km stampede in October, you can do this, and more.

Shake your fist at your nebulous concerns, and then go practice your spear tossing. Spear spearing? Spear flinging?

And then go for a run.

And then eat a live heart. Or something.

You're gonna smash it, and then come in here and whinge about all the people who (like me) walk between the different crazy tasks.
