Ouch! I've spent the last 2 days in lots of pain! On Thursday night I did my 1st track session in about 4 years. I expected to maybe have tight calves on Friday but the pain I've got in my left hamstring is much much more than expected!! I did a long run this morning and going up hills was quite nice but coming down the hills was very painful and just to add to things I have now tightened up my back!! I am feeling happy though as I had a really good session and ran much faster than I thought I would. Lets just hope that tomorrow's long bike ride sorts me out!!
