Whining by the Numbers

Today I went to walk with the St Croix Valley Runners (& walkers) and found myself alone - plenty of runners but no other walkers.  So I took off at an 80% walking pace and went about 3.5 miles in 50 or 55 minutes.  No problems today except the right knee.  Here is the whole catalog of issues six days after the OC Marathon (this might be TMI - read at your own risk):

1. Right knee: Pain appeared on the outside of the joint after the marathon, bothered for a few days and went away.  I felt it just slightly today but it went away after about 45 minutes. 
2. Right ankle: Showed up at the foot after the marathon, bothered for a few days but only when walking fast, no problem today. R
3. Right heel / Achilles' tendon: Bothered a little in the race, nothing since. 
4. Blister on left big toe: Not much change.  It's between the two toes, and I don't understand what caused it - first time in 95 marathons.  It isn't healing fast (nothing does on my feet) but it's also not bothering at all.  Mostly I keep it covered with a blister patch wrapped around the toe, and I suppose I'll do that in the next marathon. 
5. Left groin: For a few days after the race this felt like a sports hernia, but today when I do a situp it feels equally sore on both sides.  I don't know what it is, but it doesn't bother while walking fast, so it's probably not a problem.

Right now nothing in this list seems likely to interfere with running the Fargo Marathon in two weeks.
