W: Well. Allen, the mountain-lake cycle tour is a two-day bicycle tour from Ottawa to Kingston and back. It is not a race, but more like an endurance test for recreational cyclists. People do it for fitness and fun and try to better their time every year. M: How long does it take to cycle one-way, Marilyn？
W: About seven to nine hours for the average cyclist. Racers can do it in four hours. But as I said, the tour is not intended to be a race.
M: How many people will be taking part this year？
W: This is our biggest year ever. We have twelve hundred cyclists registered.
M: I'd hate to be on the road when the cyclists start out.
W: Don't worry, we've introduced staggered starts to avoid these problems. Our first group will leave Ottawa at seven o'clock, and other groups will follow every twenty minutes.
M: Thank you, Marilyn. Now down to the starting line of the university.
