Probably about that to be absorbed and used - though, trials show you can fool the brain into thinking you've had carbohydrate by rinsing your mouth out with a carb solution and you still get a performance increase: http://www.ncbi.nlm.nih.gov/pubmed/19952850 not sure how long this effect takes.
My cousin swears his caffeine containing gels worked in last weekend's HM within less than 5 minutes each time.
It depends on the gel and the individual - surprisingly! Some contain about 10 -15% fructose which can be absorbed and utilised within 2 or 3 minutes. The other 85% is normally maltodextrin which can take upto 20 mins to be absorbed - so you get a continuous supply of 'extra' energy throughout this timeframe.
and if they're caffeine loaded gels, you can get that caffeine hit within a couple of mins and before the carbs have kicked in - it can feel a bit like a rocket boost
Shelly, proof / data from consumers of gels? If you are looking for good and bad research data would the manufacturers / researchers be a good starting point, or get reading Tim Noakes for some unbiased research.
caffenine gel?? where can I get this caffenine stuff?? is it any better than caffeine?? I need to know. and I need to know now. I can't be arsed googling for caffenine as it keeps saying "do you mean caffeine?". just tell me now!!!
Bing and google searches don't give links to research on this topic. I don't want opinion articles. I am not asking for you to do my work. I am reaching out to the friendly running community to see if they have come upon any research. I don't want you to waste your time responding unless you can be helpful. And no I am not bad tempered, I am actually quite nice and joyful.

So your cousin may be right, Daeve

Too many variables anyway, some one FB's or my size can metabolise a beer quicker than a midget, I expect the same is true for a gel..
Always worth trying them out during training
Try google!! it took me 2 minuteds to find half a dozen pier reviewed articles on said subject
sorry Cougie - x post!!
(and is it just me - or does she come across quite arsey ?)
maybe its caffenine gel withdrawl?
;-)

I see you're on LSD now, FB
Not trying very hard Shelly.. I googled "sports gels research" and first hit of thousands was
http://www.ncbi.nlm.nih.gov/pubmed/18076252
http://www.ausport.gov.au/__data/assets/pdf_file/0003/462882/Sports_Gels_11-_website_fact_sheet.pdf
and that one has a link to further reading

Should I go on ? and fancy a go yourself
These are just some I had lying around the place

I'm in a good mood have another one
Clearly Dave and Rafiki are in on it too !
I'm trying for a degree in googling
Now you can work on "Thank You" to the nice runners who have found the papers you wanted.
In her defense, google or bing are not that good at finding research papers. Although Dave is obviously masterful in its use!!
Shelly - if you use Google Scholar, it'll give you a lot of good reference material
