    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?

    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
