Stupid Knees!

Today is a terrible day for me right now the knees are killing me and some other problems with my right foot in alot of pain so today im going to take it easy and walk 4 miles instead of the walk/run I've been doing. I was afraid this was going to happen, hurt the knee in May on vacation and now its bugging me alot, so in an attempt to give my knee a break I will walk instead of run. Plus tomorrow I will be hopefully picking up a trainer for my bike! It sucks that Cycle Sonic is closing but a plus for me because i may be able to get a steal of a price on a good trainer. So now I can ride my bike when it's cold outside and to be honest I'd rather be on my bike then running, I love riding too much.
