M: And here’s our guest,[12]Jane Thomas, to tell us about Montreal’s famous yearly Island Bicycle Tour, which is coming up in June. Good morning, Jane. What’s the bike tour all about?
W: Well, Peter, it’s an event that’s open to anybody who’d like to ride a bicycle through the streets of Montreal.[13]The tour covers a standard distance of 65 kilometres, but the route is quite different every year; so even people who have 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, what’s the typical pace for a participant?
W: Between 12 and 30 kilometres per hour. Some cyclists stop along the way and don’t cross the finish line until early evening.[14]But the whole point is that there’s no rush—it’s not a race.
M: I understand last year’s tour had 45,000 cyclists. That 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 prospective cyclists?
W: Yes. Take water with you. It is available at the relay stations, but it helps to have an additional supply. And pack a good lunch with plenty of fruit for energy. Candy and chocolate don’t do the trick.
