Its nice to see some agreement on the drinking/fuelling issue.
I stopped runnning for a while and when I started again it was as if I had woken up in a parallel universe. Reading some comments you would think people were in danger of dying if they had to run more than 2 miles without a drinks station.
For me, theres no need for drinks of any sort on training runs and that includes 25 milers, intense workouts etc etc. Hydration is what you do before and after a session not during.
I've certainly tried drinking on long runs but didnt notice any particular benefits. The only effect seems to be to make pee stops come into the equation, suggesting that the liquid was unwanted by the body anyway.... talk about ungrateful.
Regarding gels, again I've never taken one but am not convinced of any great benefit that cant be achieved by training. There were no gels about during the 70s/80s when much faster average times were being run and the very fast guys now dont seem to bother with them ... so I suspect theres a strong 'placebo' element to their supposed benefits. People report feeling a 'rush' when they've taken one but that would happen with any increase in blood sugar and doesnt necessarily mean that it has translated into increased muscle glycogen to enable someone to run longer.
The fact that a lot of people taking gels have training and racing paces that are pretty similar would suggest that they are not in danger of glycogen depletion anyway.
As a general rule, I would say it is always better to avoid introducing anything into the stomach during racing if at all possible. As soon as you do so, a certain amount of bloodflow will be diverted towards the stomach and away from the active muscles possibly leading to cramps and.or reduced muscle performance.
