DOMS

I went for a run two days ago and I am now in agony! Delayed Onset Muscle Soreness is caused by unusual exercise of muscle groups and is probably a result of minor tissue damage caused by the exercise. As I get older, I find that DOMS kicks in much sooner, for example, I cut a hedge last week and after only twenty minutes of exercise, I was sore for several days.
The good news is that DOMS is only caused by unusual exercise, so repeat the exercise regularly and the pain will be much less. Its a sign that the training has worked, in fact its a sign that the training has been optimal.
So, I've had a days rest, time to load Runkeeper and head off again!
