Hydrating 4+ hour rides w/o stopping to refill

Equipment
39

I take 2x 1L bottles and just refill at a public park or wherever I can find water. Some of our dedicated cycling infrastructure here has water fountains which makes things easier. Don’t stress the stopping to fill up, it takes no longer than being stopped at a traffic light. Coasting a lot is going to have more of an effect than a brief stop to refill water.
