Okay, this might be a bit weird but I’d love to know the science behind it.
Like most people I know how much water I should be drinking, but chugging it down in sufficient quantities is just a chore and I don’t really drink that much plain water during my day. But as soon as I hop on the trainer, I find it really easy to finish a 600ml bottle (usually with SIs electrolytes) within the first ten mins or so. In fact, I often plan an extra bottle for the start of the ride and I’ve gone as far as extending the warm up by 10 mins just to sit at about 35% FTP and take down some fluid before pressing on with my workout.
So, what gives? Why is it that my body just seems to find drinking fluid so much easier when I’m doing some light work? Is there a change in physiology which enables me to uptake water and electrolytes more easily? I’m starting to wonder if I need to sit on the turbo just to get properly hydrated! @chad I’d love it if you could turn your powers of investigation to this!
