In a little over two weeks, Ray Porter of Oak Cliff will attempt one of the most challenging bicycle races in the world. Porter, 54, started the 2,745-mile Tour Divide two years ago, but he had to quit after about 900 miles.

He told us the whole story last year as part of our September 2010 cover story about hard-core amateur athletes.

So this will be Porter’s second attempt at the Tour Divide, which starts June 10 in Banff, Alberta. The strongest riders will finish about three weeks later, after climbing some 200,000 feet over the Rocky Mountains, in Antelope Wells, N.M. You can see the route here.

There is a documentary about the race, “Ride the Divide”, and the trailer, below, explains it pretty well.
