Label as you pull and you save yourself the headache plus the toner cost later.

This is the same trap people fall into with money honestly, where they look at one big number and ignore the rate. A 20 mile flat walk sounds way worse on paper than 6 miles uphill, but the uphill is doing way more work per step. I learned this the hard way too, not in Colorado but on a trip where I had 3,000 feet in 4 miles and thought it would be a quick morning. It was not. The gain per mile number is really the thing that tells you how hard each step is going to feel, and mileage alone hides all of that. So yeah, checking that number first is smart, and it carries over to all kinds of stuff where the total looks fine but the pace of it is what actually gets you.
