I've had some recommendations to try some active recovery so my body can slow down slowly and not come to a sudden stop at the end of endurance events. I will be trying that as well as focusing on drinking more. As far a finding a way to want to drink more, I think I will need to go with a variety of drinks, rather than one specific drink.
This morning, on my work ride, I tried a packet of Emergen-C in one water bottle. The result? I enjoyed it. I do think that this would get old after 8 hours, but I think rotating with the drinks that I currently use will be a great addition. I also felt good after drinking it, felt like I got a little extra kick. I'll have to try it on some longer rides to make sure it is not all in my head.
Have a great day.
