arly island bicycle tour which is coming up in June. Good morning, Jane. Whats the bike tour all about？ W: Well, its an event thats opened to anybody whod like to ride a bicycle through the streets of Montreal. The tour covers a standard distance of 65 kilometres. But the routes quite different every year. Even people whove already done it might enjoy doing it again. M: How long does it take to go the whole distance？ W: It varies. Cyclists are free to go as fast or as slow and do as much or as little of the course as they like. M: Well, whats the typical pace for a participant？ W: Between 12 and 30 kilometres per hour. Some cyclists stop along the way and dont cross the finish line until early evening. But the whole point is that there is no rush. Its not a race. M: I understand last years tour had 45,000 cyclists and it was the largest mass cycling event in the world. How many do you expect this year？ W: The same as last year. And since we regularly have so many participants, can I take this opportunity to remind our listeners to sign up early？ We filled up quickly last year and we had to refuse lots of applications. M: Before we close any other tips for all prospective cyclists？ W:Yes. Take water with you. It is available at the relay station. But it helps to have an additional supply. And pack a good lunch with plenty of fruit for energy. Candy and chocolate dont do the trick. Questions 13 to 15 are based on the conversation you have just heard. 13.
