100km at a standstill
Last week I rode the full Ventoux vid, 4 hours of climbing and descending, no way I could tolerate that length of time on a standad turbo.
<joke>That doesn’t count as a metric century, you know.</joke>
I’ve tested the fortius (twice) and it’s a pretty astonishing piece of kit, i agree. not sure i could do 4 hours on it though…
