Pursue, attempt 追求，嘗試

Welcome to Talking Sport!

This week we follow the training of the British triathlete team, including Alistair Brownlee.

Alistair is the current World Triathlon Champion.

The 24-year-old also won the title in 2009 and is one of Britain's best hopes for this year's Olympic Games.

Join Natalie in this week's video to find out more about a triathlon's training and learn the words 'pursue' and 'attempt'.
