Carbs ingested is now filled in from session field number 177 which is calories consumed, divided by 4 to get grams (assuming that is mostly carbs). Will deploy Sat AM.

Unless your doing a recovery or z2 ride youâre not going to ingest as much carbs as you will burn.
Really just a matter of gut tolerance for longer harder rides >90mins
Very nice feature, sadly it doesnât work well for rides with a lot of freewheeling (which happens all the time in the mountains). For example my today ride has CHO utilisation almost as high as calories burnt (355g CHO and 1587 kcal, meaning 1420kcal from carbs) even though I was below threshold all the time and for the most part significantly below it (which means I should have burnt some fat as well).
Do we have access to the data from the paper the calculations were done on? I am willing to spend time finding a better function if I can get the data. It wonât be difficult as the researchers based it on TSS which increases with time, not with actual work/intensity.
For me, the numbers given by this TSS equation seem too high.
I have done several metabolic cart tests and converted the data to carb and fat consumption for a given range of power.
For example 150 W â 45 g/h ; 200 W â 100g of carbs/h
I will keep beating the same drum: TSS is a metric that increases mainly with time, not actual work. It doesnât work for measuring training load. It doesnât work for approximating CHO consumption. It doesnât work for anything power related. Itâs a shame piece of good research was wasted because of this nonsense but here we are.
What would work better is using the power curve to approximate CHO consumption and then integrating over it (taking area under it). If we can get some actual data we could try to fit the curve and get some reasonable estimations.

Hi, Iâm sharing my spreadsheet here if you still would like a copy:
Thank you.
