Yes, have done Mike. I literally got let out of the hospital this afternoon so I've been mailing around various bods.
I was extremely foolish, running way too hard for my fitness in the conditions but mainly for not taking on nearly enough fluids during the race. I was totally, totally, dehydrated and got a bad dose of sun stroke.
I can't remember what actually happened, just remember coming to in the ambulance in a very confused state. I got to A+E and popped on a heart monitor and a drip. They kept me in the hospital so long as they were worried I had damaged my heart or kidneys but thankfully I seem to be ok. I was well looked after throughout.
Doc says I'm not supposed to run for 3 months which I view as suitable punishment for being so foolish. Does mean missing the Northumberland Coastal Run though

Huge thanks to the organisers for having such good marshalls and first aid it could have been a lot worse otherwise.
I am especially grateful to the two runners who came with me in the ambulance. I feel enormously guilty about them having to give up their races for me. I'm afraid I can't remember one of the chaps name, he was sitting at my feet end! If anyone knows who he is could they please let me know so I can get in touch with him to thank him.
Bit wiser for the whole experience. I will be back next year when I will be better prepared and much more sensible.
