This week has been a bit frustrating.

Monday's 'run' was good!
Wednesday's was sore. A few strides into the running bit of my run and both knees starting feeling odd. Not really painful but a sensation that felt like a warning. I listened to it and stopped running. After a few more minutes of walking, I tried running again. Knees said, 'no.' So, I walked the rest of the way, went home and pouted. (violins)
Friday, I tried again. Still, my knees did not feel right.
On my way home, I detoured into a running shop 'just to look' and had a nice surprise. The woman working there was a runner and also a physiotherapist. We chatted informally about my knees and she gave me a bit of advice which was essentially: let my knees catch up with my enthusiasm and some other tidbits.
It's very difficult to finally feel like wanting to get fit again and finding the holy grail of sports bras and finding great shoes and having excellent support and feeling very excited about trying something new... even the weather's been great! ... and having to take it slow. ARGH!!!! ;-)
But, it's just what I need to do. Simple as that.
I'm still sweating though; walking and doing some strength building and 'prehab knees' exercises but... so frustrating! lol. And I should be back to running very soon!
