It's really important for the cyclists to eat and drink while they are on the bike. In a race like the Tour de France the riders can barely keep up with replacing the amount of calories that they burn. So, they have to make sure that they eat while they are riding. Normally they will carry some small bars and gels in their jersey pockets. But, they can go back to their team cars in the caravan to get more food and bottles. There are guys on the team who are designated to help the other riders, and they will make many trips to the car. Their job is really important because they are helping the other riders on the team. There are also areas called "feed zones" where each team has people waiting by the side of the road to hand their riders bottles. They normally hand the bottles to their riders in "musettes which are like cloth purses for food and bottle. That way each rider can get a couple bottles and some food all in one bag. The cyclists have to eat so much every day that they actually get tired of eating and have to work hard to get their calories. So, sometimes the teams add some of the riders favorites in their musette bags... Things like small sandwiches, and cookies are favorites...
