Help! My achilles Tendon huuuurrrrts!

cut down by about half your volume...2twice a week for now...see if that may help.  make sure u r warmed up before u stretch (light 5min jog)  dont overstretch BEFORE running.  if it does not hurt running, u may be fine with reduced intensity.  i was able to really say goodbye to my achilles tendonitis with some trail runs that were a little hilly BUT that was when my achilles didnt bother me no more on the run...only at work.  check your shoes first too...may need a new pair.  just my own experience with this pesky injury. FOR ME, i did notice that biking irritated the achilles while i was trying to heal it...so i stopped replacing the run with more bike. 

another thought...take 4days off in a row from running...do a light run on the 5th and 7th day of the week...give it some good rest.

what been working (in cold ohio weather) for me (for now!) is to do a 'baby step' or 'shuffle' run as a warmup for about 2-5minutes.  not fast and about half of the lenght of my normal gait.  then i will do: toe touches, hamstring stretch then calf stretch, 20-30 sec each repeat 3 times.  dont go where it hurts and dont push your limits..i would say its about 75% of your max flexibility.  only go until it JUST STARTS getting tight - never anymore before a run.  i used to go till where i was noticeabley at my limits - thats bad.  that contributed to my tendinitis.  dont stretch immediately after (if at all)...wait till a few hours later.  gallaways book on running has some great stretching tips in it.  i guess the rules emphasized (i may be repeating) is to warmup with a reduced shorter stride and lower pace, then only lightly stretch.  it seems like only lightly stretching will help but stretching near your limits or at the pain level is only setting yourself up for injury.
