510.47 miles year-to-date

I've been keeping track of my documented miles for the year. There's a couple of periods during the year where I didn't record how many miles I ran, but I've been running consistently all year long, with a 3-week break for other exercise in January.

As of tonight, I've documented 510.47 total miles since 1 January 2006. There are 8 weeks left in the year. I'd like to aim for 20+ miles per week but the weather is going to get worse for longer runs.

But assuming I do 15 miles per week, at least, that will give me an end-of-year total of 630 miles. I wonder if I should aim for 650? Or just be happy if I go over 600?

Hmmm... glass half empty or glass half full?
