Looks like the schedule is posted for the 2007 National Ultra Endurance series. There are seven races as follows:
Apr 21 - Cohutta 100, TN
June 2 - Mohican 100, Mohican State Park, OH
June 16 - Lumberjack 100, Manistee National Forest, MI
July 21 - Breckenridge 100, Breckenridge, CO
Aug 4 - Wilderness 101, Coburn, PA
Aug 25 - Endurance 100, Park City, UT
Sept 2 - Shenandoah Mountain 100, Harrisonburg, VA
Looks like I should be able to hit at least a few including Mohican, Wilderness and Shenandoah. We'll have to see about Lumberjack and the western races.
New bikes should be ordered in the next day or so and delivered next week.
