And if you have done it before you CAN do the entire thing without walking!! Keep out of your head! It's all mental, or as the Aussie dude on the Kona show said "It's all up top". We believe in you, now believe in yourself (not that I think you don't, just sayin) and go out there and have fun!
I'll be thinking of you!!
Slow down if you must, but keep a jog on. And remember my mantra "the faster you run, the faster your done"...
Cheers!
