WHICH JOURNEY COMES WITHOUT CHALLENGES?

I guess none that involves me! After having some knee/IT band problems during my training for the Toronto Marathon back in October. I'm getting some intense calf pain in my left leg... I missed my 3 mile recovery run today to give it a break. I iced it a lot yesterday after my speedwork and some more tonight. Again, I just wish this is not something serious... I am thinking of doing 4 runs a week instead of 5 for the time remaining before the half. I know I will be running Hal Higdon's Novice II shedule for my May marathon so I will switch soon to 4 times a week anyway. I don't know why I feel like I am quitting something... And I don't want to be a quitter! But I guess I have to listen to my body as is telling me that running 5 times a week is just a bit too much right now. Especially in this weather....
