That's a non-stop traffic controlled ride where the rider is probably riding pretty hard, for ~ 12 or 14 miles depending on the race.
I did a Tri last summer in which the men's over-all winner made 27mph for the 11 mile course.
Also, I made 18.0mph (moving average) this morning
, and I usually make between 17.0-17.8, sometimes as fast as 18.4
(It's fast for me, regardless of how fast it is for anybody else
)
