Chris, Texas has a toll road that goes from north of Georgetown to San Antonio that's posted at 85mph.
As far as shortest time to do 1000 miles, I don't have any idea. My guess is that it was probably done in Nevada or Montana (before Montana had daytime speed limits). There's one guy who did 10 consecutive 1500 mile days on a Honda Blackbird (the CBR1100XX). He had a pit crew who serviced the bike at the end of each day while he slept. I'm sure that ride was done entirely in Nevada.
There have been at least two Ultimate-Coast-to-Coast Rides (Prudhoe Bay to Key West) ridden in under 100 hours and one of those was way under 100 hours.
The Saddle Sore 1000 only takes a 41.66mph average speed. On the two of those I've certified, I spent lots of time stopped. On my Connie when I did the first one, I was in fog from Big Spring, NE, to 60 miles north of North Platte. We spent about 45 minutes stopped in North Platte hoping it would burn off. Then we stopped for two hours during a torrential thunderstorm at Sturgis, for another 45 minutes at a Dairy Queen in Gillette, WY, trying to rehydrate ourselves after riding about 100 miles in 106F temps. When we got Cheyenne on the way back, it was night and another torrential thunderstorm hit and we sat for another hour or more and got home in 19 hours and 10 or 15 minutes.
On the BB1.5K (36 hours with another 42.66 mph average required) we stopped for an hour in Trinidad to warm up after riding 250 miles in temps of 24F (without any electric gear). We stopped for over an hour in Amarillo, an hour in OKC, slept for 2 1/2 hours in Hutchinson, KS, stopped for over an hour in Plainville, KS (again after riding for about four hours in temps of around 20F), then for 45 minutes in Holdredge, NE, and 45 minutes in Wray, CO. We cut that one pretty close, taking 35 hours and 10 minutes.
On my NT SS, I stopped for 30 minutes at Flagler, CO, 45 minutes at Springfield, CO, an hour at Dodge City, 20 minutes in McPherson, KS, 20 minutes in Salina, an hour in Hays, KS, and 30 minutes in Limon and got home in 20 hours 50 minutes.
On my BBG attempt, I blew it early and late. I had blown it before I even left by being rushed in preparation. I'd had three funerals the week before I left and had some kind of maintenance I had to get done before leaving. I don't even remember what it was, but I had the mid-fairing and the front fairing off and on the day before I left, I could not get them back on. I finally called a mechanic friend and he came over and we got it done by 10:30. I was planning on a 4PM departure and had wanted to be well rested before leaving. Guess how much sleep I got on Monday might! Then as I was finishing packing the bike, I discovered that I had a flat rear tire. I spent an hour or so plugging that and then I programmed my GPS.
The BBG takes a 62.5 mph average speed and that doesn't leave time for messing around. I hit two construction zones in the first 80 miles and was 45 minutes behind the pace when I got to Limon. I wasn't smart enough to simply reset the clock and begin the BBG again in Limon. It would have been easy to do. I made a mistake in Kansas when I passed a gas stop at Colby and then was afraid I was going to run out of gas before WaKeeney. There was a gas station in a little-bitty town but I didn't know if it would still be open at 8:30, so I slowed down to about 50 to guarantee I could make it to the next one, 12 miles farther east. Turns out the little one was pay-at-the-pump (but the receipt writer was broken. I "documented" the stop with pictures and since it wasn't a corner, don't think the IBA would have given me any trouble about it. I also think I would have made it to the 2nd station without slowing down, but I might have been on my last tenth of a gallon.
Things went well for me till I got to Des Moines. I was on pace, but with no margin for error. When I left Des Moines, the GPS started telling me to turn to the west at every semi-major intersection. I couldn't figure that out because my next corner was Albert Lea, MN, due north of Des Moines on I-35. It finally struck me that I hadn't entered Albert Lea into the GPS.
Frack!
So I had the GPS calculate the quickest route to Spearfish. It turned me onto US-20 heading for Sioux City. But. There was construction which was turning 20 into a 4-lane highway. The construction dumped me out into the middle of nowhere 10 miles north of 20 on an old county road. Then there was construction all the way through Sioux City. By the time I got to Mitchell, SD, I had something like four hours to do 250 miles and I was going to have to go to at least Sundance, WY, and back to Spearfish to get the 1500 miles. I was going to need a minimum of three gas stops and one of them was going to require filling up. The other two would mark the corner at Sundance and stop the clock in Spearfish. The GPS was telling me that it was going to take me four hours and 20 minutes without any stops.
So I bagged that attempt and learned some lessons for the next one. I think I ended up doing about 1320 miles in the 24 hours.
