Welcome to Talking Sport!

Today we meet German horse rider, Hinrich Romeike.

As well as being an Olympian, Hinrich is also a dentist.

He works 5 days a week and trains his horses in his free time.

Hinrich is aiming to compete in the 3-day eventing competition in Greenwich Park as part of this year's London Olympic Games.

Join Natalie in this week's video to hear about Hinrich's daily routine and learn the word 'entirely'.
