Adrian Kloet has survived the 6,246-kilometre Sea to Sea cross-continental bike tour.

Mr. Kloet, 65, rode the Seattle, Washington, to Denver, Colorado, leg of the tour.

"The trip has been challenging," Mr. Kloet said last week. "Cool nights and hot days with temperatures climbing into the 100F. We are very thankful that there have been no serious injuries."

During the tour riders hope to raise more than $1.5 million. The money will be used to fund initiatives that range from stopping the spread of HIV/AIDS in Africa to improving crop yields for Central American farmers. The tour began June 28 in Seattle, Wash., and ends nine weeks later in Jersey City, N.J., on Aug. 30.

Mr. Kloet said the cyclists' daily routine starts at 5:30 a.m. by taking down their tents, getting dressed, making lunch for the day, eating breakfast, then getting underway by 6:45 a.m.

"By noon the temperature starts to wear you down." said Mr. Kloet. "I have been trying to get to the day's destination by early afternoon."

Mr. Kloet said last Thursday's ride was one of the most challenging. It was 154 kilometres, with cyclists climbing 5,000 feet.
