Hi Mike and everybody (if anyone is still reading this thread)
I am just back from COMPLETING the Paris Marathon, 4hr 36 which ranked me 46 out of 121 in my group! I am over the moon - and if my knee hadn't hurt so in the last 3 miles, I could have done better... Already thinking about another!
Just an "I wish I'd known that" tip for you FLM-ers: if its forecast cold still for Sunday, or you are likely to be nervous, take a gardening/painting sweater that you can afford to ditch, or get one from a charity shop. Everyone just peels them off at the start, and I understand they are given to charity. I was shivering in 6degrees in Paris, and the bin-bag was ni help!
Above all, savour the experience - for me it was once in a lifetime (I said) and I was so ecstatic to be part of it. Best of luck - have a good race.
