... plus I have a heating pad on my right achilles in the hope that it will (please!) stop hurting...
Good luck keeping that thing in check. I'm still dealing with mine as well, but it seems to be getting better. Took those 8 days off, doing nothing but a flat hike and a little time on a stationary bike, while putting heat on the achilles 2-3 times/day to encourage the blood flow. It was feeling better, so ran 5 on Friday, 5 on Monday, and 6 today. Keeping it all down off the trails, on flat bike paths and roads, as I know running up hills strains the achilles more. So far, so good. It's definitely better than it was, although not 100% yet. I miss the trails big time, but this is better than those 8 days of no running! Want to give it until the end of next week, running 5-7 flat miles every-other-day or so, and then see how it feels. Have given some thought to maybe doing another road marathon this fall instead of a trail 50K, as I think the training for that would put less strain on it. But that's a fallback plan, as I still hope to get another ultra in this year.
