Running Totals - January to June

At the beginning of the year I joined a 1000 mile challenge on the Nike+ site.  I've never managed 1000 miles in a year and I would like to reach that this year.  Through 06/30 I have run 538 (not all those are synced because Nike + is having some sort of connection issue).  I'd say I'm on pace to reach my goal if I just keep on.
