My order would be:

1 - this is simple. It will work in many installations, from business cards to websites to t-shirts, to listing on an exchange. It is nicely identifiable. I don't have to think to know what it is about.

• suggested improvements: make the circle a bolder colour - like the red from logo 2

3 - this is a nice stylized logo, but I'm not sure what the crescent represents. When you make this much smaller as on a listing page on an exchange, I think it will not be bold enough to be recognizable

2 - this is a bit too busy / abstract to be easily identifiable as a runner. Again, when this is made smaller you lose all sense of what it is representing.

Just my thought on this - keep the logo as simple as you can. You want it to be identifiable without thought, or squinting to see it better.

Think of the Nike tick - very simple, works everywhere, adaptable.

I want a logo that also looks good on a shirt so I can wear my RUNCOIN shirt when I'm out running and let everyone know - I get paid to run! hehehehe
