After spending three weeks off on the IC with a pulled Achilles tendon and doing heel drops and stretches it felt OK so I tried running gently today. Everything went well for four minutes then I began to feel it tightening up again. slowed to a walk for twenty minutes then tried again. Three minutes in and OUCH. I spoke to the trainer who told me it took a good ten weeks to an Achilles tendon to heal. What a bummer! I have missed the runs so much but don't think it would be a good idea to continue forcing the issue. It's so demoralising when I worked so hard to get to 6k+ and was working towards a 10K. Looks as if that is out of the window now.
