Running update for 8/23

So I haven't updated in a while but I've been running a ton lately. Let's just skip to the current week...

Tuesday: 4 miles, treadmill at the hotel
Wednesday: 10 miles, Upper Newport Bay Regional Park, and Balboa Island
Sunday: 20 miles, chicago lakefront from the Aquarium to the north end of the path and back

Total: 34 miles

Only four weeks until the marathon! With today's run I feel totally confident! Is anyone else running the Chicago 1/2 next weekend??
