Saturday Morning Run

As most people know my achilles tendon has been very tender as of late...pretty much since the marathon. I got my 'free' Brooks Running shoes as a gift from the race. I am thinking that those shoes are flaring the tendonitis. Is that possible? I ran today in an older pair of Mizuno's and ran without pain. Hmmm. I think I am going to try the Mizuno's again tomorrow for my 14 miler and see the pain level. If I am pain free I am going to get a new pair of running shoes. I hate to spend the money...but more importantly I HATE to be in pain when I am getting into some long runs prior to the Disney Marathon.
