Just wondering what the general consensus is on the accuracy of Zwifts algorithm in terms of rider height vs speed?
I train with a friend both on Zwift and on roads, when we are out and about he destroys me, but when we are on Zwift I am able to drop him, so something doesn’t seem right.
We are both using calibrated smart trainers with our real height/weight numbers, so I don’t think there is a problem with our equipment or setups.
I have noticed that a lot of A/B category riders seem to be a specific height/weight, there do seem to be an abundance of riders around the 170cm / 70kg mark, but that may just be to do with the distribution curve of the population in general more than anything else.
Still, there are definitely a few youtube videos around, which seem to suggest than changing a rider’s height in their Zwift profile has a HUGE impact on ride time of say a 1 hour ride, with taller riders taking several mintues longer than shorter riders (with all other stats equalised).
Any tall riders out there who train with shorter guys having similar issues…?
