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.
