Obviously I wouldn't be so irresponsible as to suggest more alcohol is good for you, but my very short-term, unscientific experiment following my last post has shown that better hydration = better running. I have struggled for the past two or three runs to keep going for 30 minutes straight so yesterday and today I have made a concerted effort to up my liquid intake. I haven't reached 2 litres a day yet, but I have had at least half a litre more and this evening I had a glass of water about 90 minutes before I went out for my run. I can't say I went from elephant to gazelle but I kept going for 30 minutes without stopping at all and, totally unexpected, Strava says my pace has improved! I also found I got back to a normal temperature quicker.
I've very quickly become a running bore at work. I can see now I'm going to add water bore to the list of reasons people will have for avoiding me! Thank goodness for this forum, full of like-minded people, to save me from seeing the stifled yawns and rolling eyes of my poor colleagues who must wish I'd find another hobby!
Happy running (and water-drinking!)
