The Science of Cycling and the Tour de France

The Tour de France begins tomorrow, about two months after it was scheduled to begin. As an avid cyclist I enjoy watching it and I find that it provides some neat opportunities for science, health, and physical education lessons. Here are some of my go-to resources for teaching and learning about the Tour de France.

The Science of Bicycles and Bicycling
There is a lot of physics involved in casual bike riding and in racing. Here's a selection of videos that explain the physics of bicycling.

The first time that you ride in a pack of experienced cyclists you'll feel the power of drafting. Besides their incredible fitness and bike handling skills, drafting helps cyclists in the Tour de France move quickly. The following video explains how drafting works.


Minute Physics offers two videos about the physics of bicycles. In How Do Bikes Stay Up? we learn how bikes stay upright, how design and weight influences balance, and why bicycles are difficult to balance in reverse. The Counterintuitive Physics of Turning a Bike explains how we turn bicycles.




The Diet of a Tour de France Racer
I've done some long days on my bike over the years including a double-century ride and at the end I've always felt like I could eat anything in sight. That's because I burned thousands of calories. But even then I didn't burn the 6,000-8,000+ calories that a typical Tour de France racer burns every day of the race.

What does it look like and feel like to eat like a professional cyclist? That's what the Wall Street Journal's Joshua Robinson set out to discover in his 6,000 calorie challenge. Take a look at the video below to see how he did it. Pay attention to the professional cyclist at the 2:40 mark in the video for commentary about energy gels because it surprise you and make you rethink the whether or not the average weekend warrior needs the expensive "sports energy" products for a simple hour workout.


If you want to get into a bit more of the science of nutrition of cyclists, take a look at this video featuring the team nutritionist for EF Education First's professional cycling team.

Take or Create a Google Maps Tour of the Tour de France

The Tour de France started today. We may never ride in the race, but we can virtually tour this year's race route through Google Maps. Just as they have for the last few years, Cycling the Alps has published a Google Maps tour of the race. You can zoom in on the course, see the elevation profiles of the stages, and navigate through the stages using Streetview imagery.

Applications for Education
Rather than just viewing a tour of the Tour de France, have your students create their own virtual tours with the Google Earth Tour Builder. Students can use the Google Earth Tour Builder to create placemarks containing pictures, videos, and text about the unique aspects the towns in which stages of the Tour de France conclude.
