Hello all. Have posted on the parkrun thread but thought I would ask here whether anyone has had this. I started running last summer, just doing parkrun each week, but did my first race in February, a 7km one, which I really enjoyed so have entered a few 10km races, the first of which is a week on Sunday. I ran 10km on Monday evening when I got in from work and although the run itself was fine I had a horrible stomach ache afterwards which came on about 10 minutes after finishing and lasted all evening. I still felt like I had indigestion the next morning. It felt like trapped wind but also a bit crampy and it was just really uncomfortable and completely ruined the good feeling I'd had from running that distance for the first time
It probably didn't help that I ate dinner about 20 minutes after getting in from the run which then just sat there waiting to be digested. I know I can't really eat much before running, and so only have a banana about an hour and a half before running in the mornings. When I ran on Monday at 6pm I hadn't eaten anything since lunch at 1.30.
I had been wavering about whether to sign up for a half marathon if the 10km went well, but I couldn't run that distance without having eaten more than a banana, and really don't want to feel rubbish for hours afterwards. Has anyone else experienced this, and if so how did you deal with it?
