In todays KCL we rode 37km. However, in the beginning it said 30km to go. Noticed it myself during riding, but also saw it on other streams.
The km ridden increased quicker than the km to go decreased. It can also be seen in this stream:
At the start 30.3 km to go, halfway 18.8km ridden+15.4km to go = 34.2km and at the end it is the correct 37.8 km ridden.
