Fly me to the moon...

Easy 8 along the trail with Jeff and Sasha.  It was hard to get up at 6 after finally going to bed at 4.  I felt fine during the run, but my knee was giving me trouble throughout the day.  It especially hurt going up and down stairs.  I'm not sure what the problem is.  Total time was 1:03:40 (7:57/mile) for the 8 miles.  I finally caught the 8 minute guy on the last mile.
 

This was not a good morning.  I woke up to my alarm clock, but then fell back asleep.  I woke up again later and was late getting out the door to meet Sasha.  I couldn't find my keys and had to borrow my wife's set.  I met Sasha and Jeff, but I wasn't sure how many I could do with my knee giving my troubles.  It felt okay for the first half mile or so, but then it started hurting again.  I thought about turning around after 2 and probably should have, but I kept going until 3.  There were a couple of times when it felt like my knee was going to give out.  It was a sharp pain on the side of my knee that caused pain up and down my leg.  Strangely though the knee felt a little better after each time.  I turned around at 3 and headed back.  It was doing okay until I hit the uphill spiral after the tunnel under Geneva Rd.  It really hurt to go up that.  I continued on to the 5 mile mark and then stopped.  I tried to run a little bit farther, but it hurt too bad.  I ended up walking back home from that point.  I've never done that before.  I've never had to cut a workout short and walk home.  I've never really had an injury like this, and I don't like it.  I'm not sure what the problem is, but it started after my day back on the 30th.  I had some pain after my run that day.  Perhaps it was too much or too fast after 10 days off.  I wouldn't think so, but I know my shoes aren't helping the situation.  I need a new pair.  I'll see how it feels tomorrow, but I don't think I will run on it.  I spent most of the day limping around on it.
