This may have been posted somewhere else given the high number of sugar-related posts have in here, but I couldn’t find just what I was looking for, so here it is:
I went on an endurance ride today (a little over 2 hours) and felt good overall up to 90 minutes in. I had waited until then to fuel as I didn’t really feel the need and all metrics (including RPE) looked alright. I took what must have been 50 - 70g of sugar (75-100ml of maple syrup from a flask) chased with 2-3 mouthful of water and I almost immediately felt RPE go way up. There’s also a clear disconnect in my decoupling chart from that moment on.
Is this something anyone else experienced? Any idea what could be causing this?
