42 miles? Using the 100 cal/5 km calculation, that's 1352 cal. That's what I would go with.
Strava appears to use speed. So if your average speed on this ride was, say, 18 km/h because of the climbing, Strava figures you haven't worked as hard as if you did a ride at, say, 22 km/h on a flatter ride.
But if you're trying to lose weight, just go with a lowish number of calories burned. Going low makes up for an extra calories you might have consumed.

I must be missing something. You're saying I should use 100 cal/5 km regardless of speed or elevation data?
