Why are cyclists riding fast together in straight lines?
Riding fast together in lines is called a “paceline” or pacelining. Usually only higher level riders (18-20+mph) will paceline because it cuts wind resistance at higher speeds. When you see a group pacelining, you’ll notice that the leader will drop off to the back, and another cyclist will take their place. That’s because the lead rider is absorbing most of the wind resistance, and is doing most of the work. As the leader becomes tired, they’ll pull off of the front and let someone else lead. Watch any professional cycling event and you’ll see them pacelining throughout the race.
