So, for the sake of argument, say 50k/h vs 40k/h.
One I can do without a massive struggle. (TT bike, flat road, appropriate gear... not such a problem)
The other isn't something I'd even dream about.
That's a shade over 31mph. I can do that for a minute or two at a time. Hard to sustain that kind of speed for very long though.
