# Tour de France Cycling Quiz

This year the Tour de France celebrates its 107th anniversary! Setting off from Nice in the South of France, the 22 teams of eight riders finish up a little over three weeks later in Paris after having cycled for a total of 3,480 kilometres, or 2,156 miles.

Although the race winds around France, (and a little bit of Belgium), the Tour de France is so long that if they started cycling in Glasgow and travelled the distance of the race in a straight line, they'd make it almost the whole way across the Atlantic ocean to Newfoundland, Canada!

## It's the climb

In the Tour de France, cyclists tackle five different mountain ranges with riders climbing the height of Mount Everest almost four times over the course of the race. Impressive stuff!

Here at Komodo we love our bikes, but could only dream of tackling what these elite riders endure throughout the race.

We also love how much maths can be found in a bike: from the angles of the frame to those circular bicycle wheels - there's so much maths in a circle. Try out our quiz to see!

## Kids cycle quiz

### All ages

1. Take a closer look at your bicycle wheel. How many spokes are there?

1. Your bike has a chainring which is attached to your pedals. How many teeth can you count on the chainring? (Pick the biggest if you have more than one)

3. How many gears do you have in total on your bike?

Hint: Use your multiplication skills and multiply your front chainrings by the number of cogs on your back wheel.)

4. How far do you travel with each turn of your bicycle wheels?

Check out this video to see how to measure it!

### Extra questions for ages 9 -11

6. What is the angle between each of the spokes on your bicycle wheel? Tell us how you figured it out.

7. What is the diameter of your bike wheel?

In mathematical language you've just found out the circumference of your wheel divided by the diameter. The circumference of a circle divided by the diameter gives you a special number in mathematics. Do you know what it is called and its value?
