Strava - calories and kilojoules

Looking at my Strava results, I noticed a recent run was measured in calories, but rides are in kJ. I don't know that much about the subject, but looking online, it appears that a kJ = 0.24 cal, this means that my 38 minute run used 564 calories but my four hour 100k only 444 calories (1849 kJ) - that doesn't seem right to me, can anyone help clarify?

Thanks, both. And that's a relief, Olic - I stuffed myself with a massive pig-out on Sunday eve, in the belief that I was only making up for lost cals!

With cycling, you can basically take the Kj figure as Kcal without a conversion as pedalling is roughly 25% efficient, so in actual fact you burnt around 1849Kcal to produce 1849Kj

That does it, I'm quadrupling my cake intake with immediate effect!

My rides list both kJ and calories.
Calories are listed just under the speed in the 'show more' detail section.
