Unfortunately he doesn't say anything about where he was from Day 4 to when he caught a ride to Phoenix. He was apparently at 220 miles on Day 4. I'd like to think that he was 160-200 miles farther along, but since he didn't say we don't know. He really should say.

Edit: Rereading his page I wonder if he rode on the weekend or not. If he didn't he is off to a very poor start and has ridden more in a car than he has on a bike. I hope that is not the case, because if he has only ridden 220 miles in 7 days with a chase vehicle he doesn't have a chance of making it to DC under his own power anywhere near on time. Even if you count the miles driven he is still off the required pace by a good bit. The pace may pick up as he gets in shape, but he needs to be making good time pretty soon.
