Good thing I got my girls

I just looked at our April running calendar - and yikes!  10 miles are on the schedule for tomorrow, 15 next Sat, 16 the next, and 18 by the end of the month.  Our mid week runs are in the 7 to 9 mile lengths.  Lately I don't want to go run - my knees are starting to ache on the runs, and my foot is blistered despite my multiple remedies.  I feel like an old lady with my aching joints!  I ordered new running shoes (with my $50 Sweetheart run winnings) in hopes of blister prevention/treatment, but now am hoping that new shoes will equal happy joints. Oh fountain of youth where are you??   Thank you sweet running girls for calling me and making me get off the couch - I need you!
