Achillies.

I signed up for the UCAP pool yesterday and did 1300 in about 34 minutes.  That was the alternative to my 12x400 which I ditched because of lingering achillies tendon pain.  I'm hoping to do another swim and then try the 16 miler on Friday.  I may do the 4 minutes on 1 minute off plan.  At a moderate pace (8 min/miles while running) - I can still belt out 9 minute miles.  That'd put me a little over 2:20.  Hopefully the walk/run will let me train through the injury.  That, and heavy doses of ice and ibuprofen.
