That should be about 300 miles total.
If you went further up the Roaring Fork and over Hagerman Pass (mountain bike ride), you could drop down into the Arkansas River. If it were a dry year you could find excellent fishing all the way to Pueblo. Last couple of years have been great all year long. Too much snow this year however. Water flows will be very high all summer long. That's good for the rafters but bad for fishermen.
Or if you wanted to turn east at Buena Vista, you could go up to the South Platte drainage and follow it all the way to Denver. Some really excellent spots along there.
