If you are with a fast pack, drop off and pick up the next group. If your pack is too slow, make a fast sag stop and leave with a faster group. Ride according to your ability Some of the faster and more experienced riders will form pacelines as the ride progresses. Paceline riding is a skill that is gained through many hours of practice and has a whole set of rules and customs. If you are not an experienced paceline rider, you should not try to be part of any paceline that forms during the ride.
Dehydration can be a problem, especially if the weather is hot.
The earliest symptom is often a low-grade cramping in the muscles. Later you may experience headaches or disorientation. Drink more than you think you need. Juices are acceptable hydrators although not as good as water or Gatorade . Don't linger at sag stops Water, Gatorade , fruit, snacks, etc.
