So, I have been running for a year or so after a bit of a hiatus to have three children. I went for a fantastic 15km run in the weekend, felt so great and then woke up the next day with what I assume is a giant pile. It is foul, I have got some prep h from the chemist but this baby is right out there and pretty sore. I have never had one before so my question is do I keep running or give it some time to calm down, and am I right that a good length run has suddenly made it appear. Possible TMI, but i have tried pushing it back in to no avail.
