Kaz - I didn't notice my hands swelling as I was too busy trying not to vom
. Well done on your 13 miles though how you can do that with no breakfast I just don't know. Does mum stand outside her house, arm outstretched with an opened Evian bottle in hand? 
DV & TD - thanks again for the advice, I really appreciate it. This is currently my biggest issue. I know I can get round, it's doing that without the nausea etc. that is the problem. Interesting point about the gels TD. Maybe that's what's causing the nausea then?
Neat idea about using a gel solution. I never thought of that. I have been experimenting with Jelly Babies instead. Used them on my last 18 miler and my insides were fine. I didn't take on any water on this run whatsoever. Maybe when it comes to race time and it's hotter I have less fluid available for digestion. However, I have always made a point of taking plenty on board on race day. Maybe plenty is not enough?
DV, the year that the nausea was the least noticeable was when I used Nuun and I think I took 3 tabs in total. I also used 4 gels on that run too.
Thanks again!
