Golden challenge to a marathon in a bad weathered day

ultraman posted this in sgrunners' forum: "actually if one can do away with the timing in mind consciously or sub consciously, one tends to achieve a much better result in timing. During any run, never let the superficial elements affect the mind. If you can do that, you will no longer a sub 5 or sub 4, but a new breed of runners with quality and speed." very true words....and i will make this challenge to myself: To complete a marathon without a watch, without looking at the time until i cross the finishing line.... anyone want to try this challenge? Not a good day for me...intended to wake for a slow recovery jog but i did not make it....not determine to get out of the bed. My hamstring are still aching over monday's intervals...so i thought a good swim after work will do it but the weather turned bad....rain came and my work suddenly piled up...got to work OT tonite. I MUST run TOMOLO!!!
