Kind of a different way of cruising a large river but thought some of you might find it interesting. In a week and half's time the the Yukon River Quest http://www.yukonriverquest.com/ will start its 13th running of the longest annual canoe and kayak race. The race is 444 miles/715 km long from Whitehorse to Dawson City on the Yukon River with some teams completing this race in under 45hrs. (that's averaging 10mph paddling) which is kind of impressive. The one team that I find very interesting is team called Paddlers Abreast which are made up breast cancer survivors who are paddling their 12th time in the race this year. They made a very good documentary (River of Life) of these women several years ago that is worth a watch if you want get a feel of the race. http://www.nfb.ca/film/river_of_life
