I'm feeling much better thanks folks. Legs are even good again.
Doctor didn't really ask or say much and I'm back for blood tests on Friday.
Of course I'm thankful that I'm well and nothing is damaged but its difficult not to be massively disappointed now. Up until mile 25 I was going well. Before I went down my legs had just started cramping and I was barely running but I knew I was nearly there.
Thanks all. I'm booked in to see a doctor later today. The medics on Sunday were brilliant from what I remember. I had an ECG in the medical tent and blood tests. My potassium levels were very high apparently.
Funny re. the Garmin t-shirt as I did stop my watch when I came around. Bet the medics thought I was an idiot. LOL.
Now I know I'm alive though I couldn't be more gutted. I wanted 3:15 and not 3:15+.
