This Sunday i'll be running a local 10k (Crown Schools) where two year's ago on a very hot day i collapsed with dehydration a couple of hundred yards from the finishing line. All i can remember is trying to scramble up over a garden fence and then being surrounded by paramedics & St John's ambulance bods. I was convinced i was running on a towpath miles way.I spent a couple of hours in observation at the local hospital and can only describe the experience as weird - feelings of disembodyment and very temporary amnesia.
Since then (including last year's race) i've always been well hydrated before races and never miss a water station.
Anybody else suffered ?
