It makes good reading - both of the posts. Here they are with some commentary.
When I see another runner, all I think is "Go on!" - maybe a little "Can I catch them up?"
Both these posts talk about the journey - like self improvement is the only possible motivation to run.
Me, I run because it's fun - but when I think back, I remember it didn't start as fun. It started as self-improvement, to work on my asthma, and shift some weight.
It's taken me three years to get to be a mediocre runner - the London Marathon elite come in with times faster than my half-marathon times - but I was even worse when I started. I was half walking, half running for the whole 2.5 miles of the flat track near where I work.
You have to start to get better, and then you have to stick at it.
UPDATE: The Self-consciousness BarrierTalking about this post with some friendly people, I was reminded of the need to overcome self-consciousness.
No-one looks their best when they run: your clothes are sweaty, your face is red, bits of you wobble, you're probably pulling a strained face.
Some people find being in public view hard enough without all that.
The thing is, no-one is really going to be paying much attention to a runner who jogs or lumbers or glides past. Even if you're in some way especially remarkable, you'll only be noticed for a second.
Runners are just part of the landscape. No-one expects you to stick around - you are moving past by default.
And anyway, the more you run, the more natural you'll look - less sweat, less red in the face, less wobbly.
