Had some bad days running, with some minor knee problems. I'm not sure if that just means I need new shoes, I got them at the beginning of the winter but have probably put over 200 miles on them, anyone know what the usual life span for shoes is?

Ran 4 miles on the Dreadmill yesterday, today I think I'll head outside and run since it was too foggy to bike into work today (now it's turned to sun, of course!)
