This week, Noah Lyles and Shaunae Miller-Uibo ... two of the fastest people on the planet! We’re in Monaco with the Olympic 400 metres champion from Bahamas and the US sprinter who’s favourite for 200 metre gold at the World Champs.

What socks is Noah wearing? Which of the X-Men is Shaunae? Who is building their own Lego city? Who started competing for their country when they were nine years old?

Those questions answered, as well as more serious discussions about comparisons with Usain Bolt, and whether some of the older women’s world records are holding the sport back. (Photo: Getty Images)
