Been there done that. Good job to finish, everyone is different and reacts to heat/humidity differently. I am a heavy and I mean heavy sweater so I cannot really keep up with hydration easily. So that means when the weather conditions are not right I have to limit the length of my rides. It is normal for me to loose 2lbs of water per hour of riding, which would mean drinking a liter/hr to match this. It can take my body 3-4hrs to get back to hydration stasis and to where I need to urinate after a 2-3hr ride.
