Caffeine kick?

Forgot to say that I tried the High5 gels with added caffeine on Sunday. I took an ordinary (ie no caffeine) gel at about 55 and 75 mins, then a caffeine one at about 95 and 115 mins.

Hard to know if the caffeine had any effect. It didn't upset my stomach, but I didn't feel any great boost (though the way I felt on Sunday's run, I'd have needed Paula Radcliffe's legs and/or lungs to give me a lift; it wasn't one of my better days!).

Oddly, after getting home, bathing, eating etc, I ended up working at the pc until 10.45 pm, which is late for me. Maybe that was the caffeine at work!

It's Lucozade gels at the Marathon, but I'm not forking out on them - I'll take some High5s with me and then use the Lucozade ones when they run out.
