I can't just cruise at that speed if I'm running 650. It's very purposeful. I don't want to say forceful, but more so purposeful. I was running with purpose. I had to focus on making sure I'm running that pace. Otherwise, if I just kind of cruise, I'll probably cruise, like, in the low sevens, like seven, five, or 710. And so, honestly, that mental piece of it was a big factor in the difficulty
