Sadly, I don't think it's an April fool's day joke.
I'm hoping they have the Nike Club Run again this year to "earn" one of the reserved spots which is how I got in two years ago. Or maybe I'll just focus on a different fall race since there's so many around here at that time. I do have the San Jose Rock 'n Roll half which is two weeks before the Nike one.
I won't take it personally, Nike. I still love your products.
