How does the energy expenditure vary when it comes to how fast one runs? Or does it matter?
For instance:
Did I burn the same amount of energy when I ran 3 miles yesterday at a very leisurely pace, could talk while running, wasn’t out of breath afterwards and then when I ran a 5k race today (basically 3 miles) at a much much faster pace (19:57 was my time) and couldn’t talk let alone breath afterwards haha
Also a lot of times after races I get horrible cases of diahrea, stomach problems, and usually will end up taking a HUGE dump 2 minutes - 2 hours after a race (not just like a huge dump, like I am in a lot of pain right before taking it from all the gas build up / have horrible aches until I do), now I usually am eating quite a lot to replenish my energy afterwards and inbetween this massive dump. Are the calories I am eating in essence “counting” in other words? Like say I ate more than I burned for a day, finishing up with the run and after run nutrition and took my huge dump, would those calories that I went over with be “wasted” in the giant dump or go towards fat gain like they normally would?
Thanks a bunch guys, just some questions that I thought about today after this year’s championship race (we won by the way 
)
