On a similar-ish topic, whenever I’m going for a ride, beforehand I need to pee and crap like mad.
Last Saturday morning, got up at 7:30am to get ready for Glentress. Must’ve pissed a dozen times before leaving the house and crapped twice. On the road there I had to pull into a layby as I was dying for a piss. Got to GT and had to run for the toilets for another pissing & crapping session and had to re-visit the toilets twice before I set off.
Now I’m not any more hydrated than normal as I drink my 2 litres a day every day and it only happens pre-ride so I think I can rule out diabetes!
My assumption is my body knows it’s going to be exerting itself and I’m excited so it subliminally lightens itself????
