This is #3. Did River Bend and 17 South - learned a ton at both. This will be the first 10k - looking forward to the physical punishment. Extra water and yes, LOTS of ammo!If this is your first one you will learn way more about you and your gear then you ever thought .
You are also only competing against yourself. Have fun don't get caught up on the numbers. Be safe bring water and gobbs of ammo. Your only goal should be to cross the finish line.
