A friend and I rode Greater London 8 as a two-person meetup with the stay-together option.
Like many who posted, we did an insane climb of Box Hill. We were hitting 29 mph with only about a 150 watt effort.
At the KOM finish we both got an exclamation mark inside a triangle. The message was we were either pros or their was problem with the sensors.
Strangest part is we disappeared from view to each other. We both saw similar names on the “riders nearby”, but I didn’t see him or his name and vice versa.
Tech support recommended I check my version of firmware for my Tacx Neo. Indeed, it needed an update. My friend has a new Tacx Neo 2 and the firmware was up to date.
