  1. I loved this article and would love to have you check out my site Keto Runners. It is all about ketogenic diets for endurance running, from half to ultramarathons!

  2. I have been doing keto for about 1 week now. Last week my long run was 7 miles. Started Keto Monday and my run was 3 miles and fine as well as Wednesday, again at 3 miles. Then Friday, when I was really in Ketosis, I couldn’t even get 1 mile in before walking. Just out of energy. Do I need to just push through it? I’m trying to train for a 1/2 marathon in June. What can I do for my energy?
