First run using stepping stones this morning. Found it hard to run at the, what I felt was much slower, pace at beginning and middle of run. I had to stop however before last 5 min as had a severe stomach cramp and really, really, really thought I was going to c**p myself right there in the middle of the park! After a minute or two I managed to start up again and complete the run without the runs! Thanks to wrong route I was miles from home and last thing I needed was long walk but JUST made it home before nature took its course! Noticed that despite feeling incredibly slow most of the way I actually ran further in 30 mins than have before, 4.7 k, how did that happen? (did not move during my break so not the explanation).
