Looks like the new sneakers have caused more problems than blisters. Now it seems I have acute achilles tendonitis. It's been bothering me since the 10M on Sunday and seemed worse tonight on the training run. The pain could be caused by hill running, but I haven't run up any more hills than usual. I can't blame it on "too fast, too soon" either. My speed varies depending on the day. I put ice on it tonight and took a hot bath. It's feeling a little better. I have the Healthy Kidney 10K this Saturday. I will skip the race if my achilles tendon is still giving me grief. I should let it heal.
