All bets are off if I am doing a long (4+ days) tour, especially one that involves sampling food from a different culture and riding that has lots of climbing. I can't do anything too unusual while riding, though. I have had some great gourmet sandwiches at lunch stops; generally, those are OK. But, most of my eating adventures involve after the ride...
Our trip to Spain was pretty strenuous. At the end of the ride, the other people on the tour generally took a nap, or went shopping. We took a shower and headed out to a bar or restaurant, where we had tapas. It was usually around 4-5 PM and everything else was closed. Seriously, some of these appetizer meals were as big as my normal dinners. So, we ended up eating 4 meals a day, though I must say my breakfasts and lunches were average or small and I nibbled during the riding, because the heat for the first few days was so awful. I needed every bit of this food and I had no trouble getting back to my normal eating when I got home.
