travel and rhum

I was hiking today and my watch notified me it had 10% battery at around the 7 hour mark. It was fully charged when I started. It’s an Apple Watch Series 3 I think? A few years old. Idk if I need a new one or what do people do to keep their watch alive the whole hike?

Perhaps a silly question but I had a hip replacement this year and I want to make the most of my newfound ability to walk without pain, but I was never a hiker. I used to run.

But how do you ramp up hiking in a way that won't cause issues? I am based in NYC and I've seen a ton of groups doing upstate hikes but I'm intimidated by things like "easy 7 miles" because I don't know if I can do that. So how do I build up confidence and mileage in a fun/doable way? Are there things I can do in the gym to help? Thanks

I was on a 3 day hike recently, going for about 6 hours each day. I took 3 litres of water each day assuming it to be enough but the temperature was much higher than I expected and ended up running out of water. It got me wondering how other people decide how much water to carry.
