Through-hiking alone: reasonable or reprehensible?

Should I hike the 500mi Colorado Trail by myself? The Colorado Trail runs 483 miles from Denver to Durango. It is mostly remote wilderness. I have been planning since last year to hike it this summer. I searched for a long time to find the perfect hiking buddy, and I've even booked my flight to Denver (June 12 - August 5). I've also purchased SPOT satellite tracking service that can summon air rescue in case of an emergency.

Now my buddy has informed me that he is $2000 short of what he needs to be able to do this trip with me. I can't afford to subsidize him. However, with a very packed schedule and less than a month until my departure, my chances of finding a replacement hiking buddy are slim. But I really want to do this hike. Would it be unwise to attempt this alone?

I'm 29 and in good shape. I am well-versed in backcountry preparedness and safety. I've spent a month in the wilderness with NOLS becoming Wilderness First Responder certified. And I think I would have no trouble "tagging along" with other hikers to minimize the time I spend hiking & camping completely alone. However, I have never camped alone, especially for this length of time. While I think it could be very rewarding, it could also be lonely and/or dangerous.

Please help me figure out a way to complete this dream of mine! Thanks.
