Thanks, that's a real help. I'll try to have fun but..... I have just rediscovered that any amount of running does still put my back out [:(]. I knew this ten years ago but it's still a disappointment. This might be my first and last attempt unless I can get rid of the pride which says walking the run amounts to failure. I'm looking forward to it though. Have a good race everyone.
Walking the run doesn't amount to failure as long as you finish. Nothing worse than a DNF.
