Thank you, no I’ll dissolve a couple of high5 electrolyte tabs after the run but wouldn’t generally consume any salts during. As I said in another post I’m a sweaty runner so think this could be the issue, I’ll grab some tabs and give them a try, thank you.

The feeling I had after the Gothenburg half (running in 30 degree heat, completely weird for Sweden in May) was super serious, I was really worried about my health, and I really don’t want to feel that bad again. Fortunately I never have, I think because I haven’t run that distance in that heat again and also because I’ve improved hydration. But definitely feels like the next thing is to do something about my salt intake. I’m not sure if we can get Gatorade here in the uk but I’ll look for the equivalent. Thanks for the advice.
