i don't read blogs on running, but i do listen to the marathontalk podcast. i can listen when i'm out on a run, and they have training tips and interview elite runners (not just marathoners, but middle distance and ultra runners too) and speak to coaches etc. The guys that run it have a decent pedigree themselves, not elite, but one of them is married to Liz Yelling, and the other is the UK organiser for parkrun, which is suppose helps explain their contacts and how they're able to get people on the show to talk to them. it's been going for 2-3 years now i think.
but i'd agree with the above posts, i'm not sure i'd be that interested in reading about someone elses running experiences unless they were a top runner themselves, or a coach, e.g. i'd happily have a read through Alberto Salazar's blog.
