sore achilles

I haven't had any achilles issues until now I've been running lots and lots of hills getting ready for my upcoming marathon. Lately after runs my achilles is tender to touch and sore,it occasionally hurts a little in the morning kinda stiff .Nothing that I would say hurts just sore,sometimes it hurts a little in the beginning of a run but then I don't feel it anymore. My marathon is on the 20th I was going to run 6 hilly miles tomorrow then 8 flat sat. then pretty much shut down just like a couple 4's . I think I'm just freaking out because it's close to the race and I just need to hear no problem it will be fine:D

You will be fine.

I think that you should be fine.  The only way that I would be worried is if you are experiencing a sharp pain.  If it is a dull ache, you should be ok.

It doesn't sound bad, but I think it would be wise to substitute a flat run for the hills, and keep all your running easy. You are at the stage where all the real work is done. Don't take even the slightest risk of exacerbating what is a very minor injury, which won't impact on your marathon at all.
