Time Trial / Time Trialling / TT

Based on what? He only gave an average HR, no indication of threshold or max values. We don't know how old he is, or how fit, or anything.

I am making some basic assumptions, but I think I'm safe in saying that someone who is new to TTing won't have a threshold anywhere near this high.

FWIW (almost nothing) I rode a 25 last Sunday at an average HR of 179bpm.... I can also tell you that I hit 23mph (my average speed)...

Did you have a headwind - both ways? Puncture? That's pretty slow.

Anyway, I was just trying to help someone who asked for advice.
