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.
FWIW (almost nothing) I rode a 25 last Sunday at an average HR of 179bpm. It took 0'52" to hit 179bpm from the start. My lap speed were highly consistent, in fact I took what time I did out of my closest rivals by holding my speed in the third of three laps where they dropped off. 23.5m of the 25 (1h1'18" of 1h5'1") were spent between 175 and 185. I can also tell you that I hit 23mph (my average speed) from a standing start in 14", and I can assure you that I've watched fast people starting in front of me and they go off much harder than I do. We slow people chat among ourselves while we're lining up at the start, and it's not uncommon, when somebody on a number ending in 0 starts, to exchange comments along the lines of "Blimey, he's taking it a bit seriously"
