There's a first time for everything. Today is the first time I've missed a 20 mile run in a marathon training cycle. Yesterday I got hit hard with what is likely rotavirus. Like puking into my trashcan in my office hit hard. After that the only thing I ate the rest of the day was about a half cup of cream of rice in the evening. Even if I wasn't dehydrated, didn't spend all night getting further dehydrated with sweating, and felt great I would have too much of a caloric deficit to attempt a 20 mile run. And so I spend this morning on the couch writing instead of training. Coach says getting healthy is the most important thing for my training. Fortunately I have enough time for at least one more 20 before Carmel and I already ran one 20 miler so I should be ok. But it is hard to skip. I might be able to pull off some kind of long run tomorrow. Or at least some kind of run. And in the afternoon it will be in the 40s so I won't be further stressing my body with cold.
