"Official" results of Vegas to Reno have been out for a couple of weeks:

It does say "official" at the top, even though they are each days results. The overall results have not been posted yet. If you really want to know the overall results of your class, you just need to take a little time and do some math.
Lets take a closer look. Primm was one day, 300 mile loop race. Vegas to Reno was 3 days, 1,000 miles, point to point with maybe twice the entries? (Not exactly sure on entry numbers, but I would be willing to bet Vegas to Reno had a few more!) Plus BITD has a prerun three weeks after and another 300 miles race five weeks after Vegas to Reno. If it takes BITD a little longer to get out overall results, I think they have a pretty good excuse.
