Can anyone tell me why some days it feels really brilliant to be out there running and the next day it is a real struggle to put one foot in front of the other?
I went out for a long run (well long for me approx 6 miles) on Sunday it felt great and I really enjoyed it. I have entered a 10K in September,and started thinking that I wasn't going to be able to do it. Hence the six mile run. My usual milage is approx 2.5miles 3 times a week with a longer 4 mile run at weekends. Was quite tired on Sunday night so didn't run on Monday to give myself a rest day. Did go out Tuesday but boy,it was a real struggle, I was breathless and found I was taking walk breaks when I don't usually. As a result when the alarm went off this morning I couldn't get the motivation to get out of bed, let alone go for my run.
Is this a common problem? Or do you think I just upped my milage too fast and need to take longer to recover?
