I also find a strong black coffee has a fantastic side-effect taken before breakfast as pre-race weight-reduction. Or if you know that otherwise there'll be a mahussive toilet queue.

I quite happily ping down 200-400mg of caffeine in tablet form before a long race.

Sounds like I'm a bad person and will surely die...

... but I haven't yet ;)

Need to go and read what it thinks is "excess". I do 1 x double espresso before hand (150mg?) and 6-8 SIS GO Caffeine gels (50mg each?) in a race, so 400-600mg. Lucozade Elite "double carbohydrate" (whatever that means!) has 80mg caffeine too. I haven't died yet. :-)G

200mg was recommended maximum. So my consumption is excessive. I didn't think it was too hysterical an article, just that there may be a link.

Did anyone understand the bit about myocardial flow rates reducing by 14-22%. Surely the effect of that would be to make blood flow more difficult and performance would be impaired. If so, wouldn't elites be shunning them (and they don't, as far as I know)? :-)G

I'm not functional without coffee in the morning, race day or not. I read that if you are used to coffee consumption, it has not much effect on you, only if you abstain from it for a longer time and then start drinking it again, as some people have already said. I also have half a pint before a LSR, what works there usually also works on race day. I'm a coffaholic :) *coffee* :D

Anyone here killed themselves to death in a marathon in the last four years due to overcaffeination, then?

Give up on coffee Dvorak, a bottle of Bucky is what you need pre race.

I did try half a cup of black coffee before long runs. It worked well enough in training but I found it had an adverse effect on marathon day, particularly is it was a warm one.

Got something to say?
