I'm in Riverside, CA now for the 15k. But I'm hurting. I went to the track this morning to do 20 min plus strides, and got all of 100m into it and knew it was not good. I did one km with not too much pain, but then it was starting to but in my shin, about mid-calf level. I tried strides for about 5 sec and knew I was done. My plane ticket had a $150 change fee, so here I am. My plan? To start the race and see what happens, and DNF if the pain is too much.
