Yes, I love long-distance running, though I've never raced longer than a 50k.
I would love to do one of those running stage races like Desert RATS or the Transrockies, where you run a long distance every day and camp out at night.
Ultrarunning is the only way to get out to the really remote stuff within the confines of a single day. In that way it resembles backpacking, and lightweight packing in particular.
Unfortunately a lot of the ultrarunning races – even the multi-day events – will not or cannot actually go to some of the most beautiful/remote places, for logistical reasons. The Transrockies seems to be an example – it looks as if very little of the running is even on singletrack trail. The aid-station people have to be able to drive in.
It would be fun to figure out how to organize one's own stage race. But I'm not sure how to do it without support – e.g. someone driving to the day's end-point with your tent and supplies. Running with a pack with even just 10 pounds in it is just not comfortable IMO.
