i've been resting my running legs for a week and a half, hoping the pain in my achilles would go away. it did somewhat. there was still a dull ache to it, but nothing like when it first happened. i was limping then. yesterday it felt good enough that i decided i'd test it out on the streets, so this morning out the door i went at 6:00. i ran slowly, concentrating on each footfall. trying not to strain anything. for the first mile and a half i didn't have any real problems. during the last half mile, my achilles went from dull ache to not-as-nice ache. i don't think i did any permanent damage, but i may take a few more days off before trying this again.
