Most Challenging Endurance Event EVER!

Week seven with the twins (isn't seven supposed to be lucky?); I have never been so tired in my life. Not through running Marathons, not through Ironman Triathlons, not though 160+ mile bike rides in the heat & humidity of Malaysia; these two 8+ pounds of feeding and fuss are dragging on me like nothing else ever has. Whatever doesn't kill me - right? Phew!
