Well I made it. I just can't figure out why the first 5 minutes are the roughest on me for some reason. After that I get into a groove of listening to the music and letting my mind wander a bit (counting the end of songs so I know roughly when I'm reaching half way). It's not easy mind you, but when I hear I'm half way though it just sort of kick starts me a bit. When I hear that I have only 5 minutes left, it's the final push.
And after I had finished and patted myself on my back, went back to my car, drank 2 liters of water and has some peanuts I saw some other joggers/runners on the trail and thought "Damn. I must look like I'm running at a snail's pace to them." And started to feel a bit discouraged. I mean, it's the third time running for 25 minutes. Shouldn't it get easier at some point? Luckily I then realized, "yeah, but you did it!" and felt a bit better.
So, does it get any easier? Any more comfortable? I'll keep pushing on, but just seems like it should start to be easier at some point.
