Maybe, but here is your original post: "Did a sprint triathlon in Long Beach this morning. 12.28 mile course in 40:45 = 18mph pace. My goal has been to break 20mph on a timed circuit. I was saving a little bit for the run, but not that much. If I had just gone balls out, maybe 18.5mph but I'm still a long way from 20mph sustained pace. But that's still pretty good, right?"

What info have you given?
How old are you?
What kind of shape are you in?
How much do you ride?
Sounds like your looking for Kudos!
18 mph would be great for me!
My son would do this on a bad day, with a hangover!
What is the point of your post?
