I have been running around three times a week for the last six weeks and have gradually built up a walk/run schedule and can now run for 25 minutes. Which is grear...but, I have developed very large bruises on the backs of both my calves. They don't feel sore (well, no more than normal bruises), but are very large and black.
Has anyone else encountered this? Is it just my poor body adapting to the new regime after a lifetime of lethargy?
