Which are the best running blogs on the web?

I agree with doug and others - http://www.dcrainmaker.com/ does his technical tests on some amazing triathlon and other globe trotting trips and with John Binns - http://www.runningshoesguru.com/ is great if there's a particular shoe you are interested in.

Shameless : How to write a blog regularly and keep it fresh is beyond me, so I write on pages and update them when I have something worth adding. http://www.squidoo/starting-running covers the hard earned lessons from my early years (too basic for you guys), but you might find something useful amongst this collection http://www.squidoo/runner-tips of solutions I wish I'd known earlier.

Personally I don't follow too many running blogs, these days I use twitter more, you can just search things like #nikepro and everyones runs and times will appear. 

However I've just started my own running blog to record my progress on a 500 mile year run, more to raise money for the charity than anything else though, have a look if you want: http://iwouldrun500miiles.com

Can I also add a shameful advert for my own blog which, like some others, is exorbitantly unpopular (but also very new). I talk about races I enter, barefoot running, running books, thoughts on running form and technique, pro athletes, etc.

I'd love any coments about the content, advice on anything I speak about, or just to see another visitor look at it, ha!

You can find it, if you want to, at: barefoottc.wordpress.com. 

This has got to be one of the BEST blogs I have seen run to be happy

Love the name too as for me it's of the main Benefit of Running!
