Hey all! First time post here, my apologies if this thread was started in the wrong area of the site!

I'm in the early stages of planning a 3 day ride in Peru in May or June of 2017. To date, the only touring I have done is RAGBRAI in 2012, 2015 and I'm about to hit my 3rd ride in a few weeks - each time we have a sag wagon to store all of our ****. So to say I'm a total noob in the world of touring would be a pretty big understatement. I enjoy the **** out of it but I've got a lot to learn.

I wanted to layout what I have planned for this ride...

*Ride Stats
Total Miles: 240
Total Climb: 9,700 feet
Max Elevation: 14,300
Min Elevation: 10,100 feet

*Gear (work in progress)
Touring Bike
Tent
Sleeping Bag
Front and Rear Panniers
Stove (maybe?)
Camelbak
Water
Food
Tools and spare parts
Standard camping **** (duct tape, blade, etc, etc, etc)

*Itinerary
1. Fly into Cusco on a Wednesday.
2. Chill for 48-72 hours to check out the town, visit Macchu Picchu, and most importantly, give my body some time to adjust to the 13,000 feet of elevation.
3. Ride approx 60-70 miles on day 1 along highway 3S. Likely camp around the lake or rivers near the town of Checacupe, Peru
4. Ride approx 70-80 miles on day 2 along highway 3S. Stop in the larger town of Sicuana along the way to replenish food and water. Camp somewhere around the town of Santa Rosa, Peru
5. Ride approx 80 miles on day 3, still along highway 3S, and stop in Juliaca and stay in a hotel on this night..maybe.
6. Ride approx 25 miles into Puno on highway 3S, stay a few hours or possibly the night, then hop on a bus and head back to Cusco to grab my transport box and then fly back to NYC.

*Questions
Has anyone ever done a ride in this part of Peru? Maybe you could point me in the direction of relevant threads on this site?

Do you think 2-3 days is enough time to adjust to the elevation? Typically i'm not really affected by it much but I also have never spent time at all above 10,000 feet.

Should I consider a water purifier/filtration system? The last thing I want to do is lug around 2-3 gallons of water at a time, but I also don't want to get myself and body into a bad situation should I get lost or have a major breakdown.

Cheers
