marathon training: mileage run #5

today marked the 5th week of my training for the las vegas marathon. we ran 7 miles today and i felt great! the arch problem i was beginning to feel in my left foot wasn't there, no pain in my knees, cardiovascularly i felt like i could have kept going... it was awesome. this after last week struggling to make it to 6 miles. amazing how different you can be from week to week. all i have to say is thank god for gu!

next week we run 8 miles. bring it on!
