Last summer (maybe the summer before that?) I was playing around with TT bars, I did a test in the park (on what was meant to be a rest day) that saw me holding 20 mph with my heart rate at or below 120 bpm for an hour.
It was surprisingly easy- the only challenge was soft pedalling up the slight incline was maintaining speed.
That said I didn't repeat the experiment with road bars under the same conditions, but I'm pretty sure what the result would have been.
