Hi, Im having the same problem, I get a sitch in the right hand side for the past few runs, my last food before a run is a snack of a bowl of cereal about 2 1/2 hours before I run. I also work my core stability muscles on my non run evenings, I will try other suggestions of breathing when other foot reaches ground, any other suggestions would be appreciated, also any other suggestions on what to snack before going out, so long as its not meat or fish as dont eat either, thanks
