I'm starting to find I'm waivering (even more than usual) in the last few mins of my runs, no doubt because of the current heat as much as general exhaustion. Is it worth taking an isotonic drink with me, or are they just a gimmick? I'm finding I can't sip my water now as it makes me feel a bit queasy. I'm also getting a blocked ear & wondered if that's not helping with my slight nausea?!
Am I just a bit weird in all this lol?
