Yer_maj, I did shotbloks in a 20 mile race and found them great. I might use them in my next marathon in October. I nearly keeled over at 17 miles on Sunday - the raisins at the next water station saved me!!
Back home now after a fantastic weekend in Paris. Loved everything about it. Was my second fastest of my 5 marathons - but was delighted with that, after being struck down with bad ITBS after the Dublin Marathon last year - last November and December I couldn't run a hundred yards without huge pain. So getting round the course only 7 minutes behind my PB was much more than I could ever have hoped for.
It's given me the bug for international marathons though... Thinking of doing Frankfurt. Has anyone else done that one? Is it worth doing?
