I have never run that far before in my life. My previous records were 7 miles, and for one hour. I was going to go for 50 minutes today, but got to a half hour and felt great, so I was like, screw it, go to an hour.
My knees felt like they had lead in them, and my feet had minor blisters, but the weirdest thing was happening: I was BARELY sweating, my heart wasn't even pumping hard, and I wasn't out of breath at all. I got to an hour and felt great still so I went to 70 minutes, then 75. I realized then that I was 25 minutes away from 10 miles. So I buckled down and did it! At the end I really felt like I could've gone for 2 more miles, hell, 5 more even. I was not tired in the least. My knees/feet/ankles weren't any worse than they were at the 30 minute mark, I was still barely sweating (my shirt was dry after hanging up at home for like 10 minutes), heart rate was barely elevated, and I wasn't breathing hard.
I think this is the first time in my life that my mind/heart/lungs outlasted my body, because my body was definitely sorer and more taxed than any of those things, even if for the most part I'm not in any pain or discomfort. Usually when I'm lifting i fail mentally, or just exhaust my Oxygen supply, or my heart can't beat fast enough to pump my blood quickly enough. This was an absolutely awesome feeling. I actually did a full abs session after I was so untired!
I get these days every now and then (I guess everyone does) where I'm just at an absolute peak physically or cardiovascularly or whatever.
I love it. I still remember the first time I ran for 60 minutes. I did 30, 35, got to 40 and figured F it, go for 60. I had never done that before, but once I did it once, I found I did it a few times per week no problem.
I posted about it in my workoutjournal (basically the same thing I wrote here)
