My boss is a Crossfit guy. He says he does 10 miles in 60 minutes when he runs. I know he is lying. Should I call him out?

A better course of action would be to take what little money you have an invest directly into personal therapy.

I’m not joking.

This is the absolute dictionary definition of insecurity.

You’re so insanely insecure that some random crossfitter potentially exaggerating his running times that you’re willing to wreck your current work relationship and make things awkward for yourself into the future.

Facepalm.

The problem is not Mark…

This seems right. After being a lifelong competitive runner I’ve only begun cycling for a few years. I’m dialed into all the nuances of running metrics but still loose on cycling metrics. I could see myself mis-speaking in a conversation around the office.

Go on about your life. You know it, we know it, he probably knows it is BS (some chance he is really oblivious).

Can't tell you how many military, former 1yr HS runners, triathletes have made ridiculous claims like this to me. Triathletes were the worst before gps watches. Always prs from the end of a tri that they could not come close to in a legit road race because they "weren't warmed up the same" or some bull hockey.

Tell him he's lying directly not in a passive way as you mentiones, and of course in front of other people.
Tell him that if he lies in important things like running he should resign because he's probably also lying about his company facts, so he might be stealing money or avoiding paying taxes, etc.
Honesty is essential in all aspects of life, starting with running!

Tell him he's a joke and that his chinups don't count either.

I've seen this before. People sometimes mistake the "level" on the treadmill as MPH. I believe he can run whatever arbitrary speed "level 10" correlates to on his brand of TM.

Probably somewhere 9-11 minute mile.

Do treadmills have arbitrary levels? Here in the UK we're using miles and km, so if you go to the gym you have to just up the pace and see which one it is. By levels do you mean km? Because 10 km/h on the treadmill would be around 10 minute miles, which is slow enough for a lot of average joes to run.

I did cross fit for a year. It was some of the dumbest and arrogant people I’ve ever met. Not surprised

It's a very strange situation, I wouldn't think about it, especially since I don't post on forums))

Please hire a student to follow you and film, mic up, start a youtube channel

Maybe he means 5 miles in 60 minutes

It's possible if his background is running. Notwithstanding Nick Barre, being that efficient at running 10 miles would be at the expense of being efficient at CrossFit. Btw, the
CrossFit "fittest athletes on earth" fallacy is the strength-endurance imbalance. A professional
CrossFit female looks more like a bodybuilder than an athlete.

You seem to be making more specific and just weird claims about things you can’t possibly know, so either he comes out on top or both of you even each other out.

Tell him to post on Strava

Then you get canned or sent to a cubicle in the basement closet. Let it go. There is zero upside to this.

You could become his PED dealer? Start selling him a random drug that isn't actually a PED for a much higher margin, or, worse give him something that will start messing with his performance, or potentially cause him to have severe mood swings and lose his job?

"Shouldn't be able to make a claim like this"

Please bring it down a notch - running is not that serious...

most likely

Let me take this opportunity to tell you to go *%# yourself you steamy pile of telemarketing pig dung.
