I was wondering too, how others were doing with their training... what have you done mileage wise for June lauraelmore? I feel like I am a little bit better prepared than I was last year anyway. I got over 370 miles in for June, much better than last year (less than 200). I did an 80 miler last weekend, but it should have been 100, since we are going to Winlock that first day - 120 miles. But I got a lot of 50 and 60 milers in, and in July so far I've done nearly 200 miles.
The only thing that worries me is my average speed, I am soooo slow... I can never really get much beyond 11 mph, so it takes me a long time. But, hey, I did it last year and lived to tell the tale. 
Is this your first STP? Where are you stopping for the night? If you've done an 80 mile ride and are stopping in Centralia, you should be able to do that NO PROBLEM.
