Sometimes when I run a long training run (upwards of 12 miles or
so) at the end, I feel like I can "taste" or "smell" ammonia. I've
always assumed that this is caused by my body depleting all my glycogen
stores and going into ketosis. I've never tested my pee with a
keto-stick, though I do have some, left over from an Atkins stint
several years ago.
Last week I ran a 16 miler in San Francisco San Francisco Long Run (Wow)
and then wrapped my clothes up in a hotel plastic bag and packed them
for the trip home. The next morning, back at home (Annapolis), when I
opened the bag, the running clothes reeked of ammonia. First time I've
ever noticed that. I didn't eat anything prior to that run and had two
gels during it (breakfast of champions). So the question is, am I going
into ketosis? And, more importantly, is that a bad thing. I think
I am and that it's bad because it indicates consumption of muscle
tissue to supply energy. But I'm no physiologist or nutritionist. So I
may be dead wrong.
