With or without music?
I used to always think I would run better having the music to spur me on... But, after running my best time ever - with out music, I decided to "test" my theory. So, today I did another one of my "typical" routes. It is a 2.2 mile loop (with lots of hills), and the best I have run it has been 21 minutes - today I did it with out music, and did it in 19 minute even with a new pair of running shoes.
Any one else find this is the case as well?
