The 11 mile run that nearly killed me

Sunday, December 27 was long run day and I did an 11 mile loop around my normal running grounds (Franklin Park, Arboretum, Jamaica Pond). The run itself wasn't bad, but I crashed afterwards. I suspect that maybe I didn't drink enough water earlier on in the day, but I was so tired and felt sick to my stomach. After several hours in bed, I did feel much better, but wow, I was exhausted. Definitely going to ask my running coach about that one today...
