M:And now here’s our guest, 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. The tour covers a standard distance of 65 kilometers, but the route’s 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 kilometers per hour. Some cyclists stop along the way and don’t cross the finish line until early evening. 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 and 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 additiona1 supply. And pack a good lunch with plenty of fruit for energy. Candy and chocolate don’t do the trick.
