Sore Achilles

[medegraa]

Hi all,

I have been suffering of late with a sore Achilles tendon in my right
leg when I ride. It started a week or so ago. My left Achilles does
not bother me. I'm trying to figure out what is going on. I haven't
changed anything on my bike.

Does anybody have any idea what may be causing this? Should I rest
it? I have been riding about a 100 miles per week. I have my first
century coming up in about a month and am concerned this nagging pain
could be a concern.

Thanks in advance,

Mike.
