Hi - love the podcast and the app. 5 stars all around.
I’m trying to discern the correlation between kCals and kJ. I’ve created a spreadsheet with some metrics grabbed from a few sources, here: https://docs.google.com/spreadsheets/d/1ZbKfx-w-lgIlVrOOhJvBWIZ3yJZfGHGfaJuCXjvaWJI/edit#gid=0
Essentially, what I’ve noticed is that my kJ and kCal numbers can differ wildly, and it seems to depend on my average heart rate. When my average heart rate is above 130bpm, kCal and kJ numbers are similar. When it’s lower, there’s a huge discrepancy.
I’ve read that 1kJ is basically 1kCal. I’ve also read that most apps use heart rate/age/weight/etc to calculate calorie burn. FWIW, I used a wahoo bolt, wahoo tickr, and quarq dzero power meter for all of the rides in my spreadsheet. I’d love to get a handle on this so I can have a better idea of how many calories I’m actually burning per day. From a bodyspec scan, I’ve got a pretty good idea of my resting metabolic rate.
I’m ivorg on trainerroad - feel free to look at my data if you want to talk about this on the podcast.
