Plantar What?

For the past few days I've been injured resting because of some pain in both of my feet.  From what I've read online, it appears to be the beginning stages of plantar fascitis.  For the past year, I've been dealing with patellar tendonitis and didn't think that I needed to worry about any other injury.  I've been good preventing PT but never thought I would get PF.  So for the past 3 days, I've been resting, massaging and stretching the heck out of my feet and calves.  As of right now, I think it worked!  I'm still going to take it easy and make sure I don't aggrevate it again.  So what could have caused it?  I can think of 3 reasons:

1.) Running in my new Pure Cadence shoes without much transitioning.   I've been wearing Brooks Adrenaline for most of the past year without issues but because of my new running form (Chi Running), I thought I can take advantage of a lighter yet somewhat supportive shoes.  I'm 85% sure this is 33% of the cause of my pain.  I'm going back to the Adrenalines next week to see I can see any changes.

2.)  I ran on pavement 2 days in a row on Tuesday and Wednesday.  I've haven't done that since last year before my 2nd case of PT.  I know I can't run on soft trails forever but until I get my milage up and get used to my new shoes, I will have to make that happen.

3.)  Too much too fast.  I didn't think I was running too much/fast but last week I ran about 28 miles.  I suppose I could have cut that down a bit (22-24) but I was feeling great last week.

I'm hoping to get my long run (12-13 miles) in either Saturday or Sunday morning.  I'm supposed to go to the beach with the family (and church friends) on Sat but the weather isn't looking great. 

Have a great weekend!
