Well I wasn't assuming it would be taken on board... If it's in your luggage it's alright, isn't it? True though, I last flew in June 2006.
To be honest, your comment was the first thing that came to my mind. We will be doing between 50-70 km per day, and it didn't even occur to me to take gels. At most some cereal bars. We are planning a really easy pace, definitely nothing to warrant that energy intake. And then I find energy gels absolutely disgusting. We biked a race last year (I took it like a nice trip, not a race, but I tried quite hard), some 60 kilometers in relatively hilly terrain, but not technical. I had one of these gel things with me... I was advised to eat it about halfway through the race, so I opened it and squeuzed it in my mouth... I almost fell of my bike, my reaction was so violent. It was GROSS!!!! I haven't had one since.
