Zwift, could you please change the settings for the avatar walk to run threshold. Some of us are not very tall and do not have a threshold at 6,8 km/h. Personally I start running at 6,3 km/h - I am 160 cm tall. And I know of others, who start at around 6 km/h. It looks stupid, when the avatar is walking, while I am sweating on the treadmill running.
