This has to be the second most difficult thing I've done in the last 6 months! And I know.. I'm just blowing my own trumpet, but who cares.. This is how good you can feel when not starving your lungs of oxygen for an hour a day!
After quitting almost 6 months ago, I decided that I should try to go for it and run a marathon (ignoring the fact that 2 years ago I couldn't run 5k without lying down for 2 days after)..
What a difference 6 months makes! This Sunday was a landmark for me in running 27k! My plan is to get over 30k in the next 2 weeks. That will be just over my 6 month quit date!
