Never heard of the National Capital Century either. But thanks for the warning. I know what areas to avoid this weekend.
Paying $50 for an all trail ride (on the trails I ride a lot anyway) doesn't sound like much fun. And I've never heard of the sponsor.
Bike DC at it's best was all road, roads closed to cars and around 8000 riders. The last one in '03 (I think) was on a miserable rainy day with only half the route closed to cars, and we still had 2000 riders.
I suspect they'll go for the traditional mid-September date, but I'm hoping for early October. Maybe Columbus Day weekend. I don't want to see it overlap the NY Century or the PPTC Century.
