Hello, I'm here just to let everyone know that calorie deficits while running really slow you down. I just got back from camp, where I ran and ate a ton, and my body is not starving, but more conditioned than before and I feel better than ever. As a runner, running should be your priority, not your diet. You become a better runner first by running, and your diet can help influence these changes, but is not the reason for changes. I ate how I felt and I was over a minute faster this year.
As a runner, your diet should also be a priority anon.
