Does anyone else get tummy pain after a run? I've had it on and off for 2 weeks now. I thought it was a bug but I've been reading about runners who have tummy problems. Any advice? I normally eat 1small avocado about 30mins before a run and have a cup of tea plus half a pint of water with a fizzy Bvit supplement (then another pint of water at the end of the run). I'm doubled up in pain about 2 hours later and then take peppermint oil to calm it down. A few giant farts later and I'm ok again (sorry if TMI!!) Anyone else with similar issues or should I see a doctor? Other than that I'm still loving my 3 runs a week. Still doing around 4.5k in the 30 mins but happy and feeling much fitter!
