340 feet, per the Google lookup on the area. Yeah, no clip ons.

The last thing though is I really want to get a new meter for that bike as sometimes it just defies logic the "aero versus power"...

FWIW, doing some double-brick duathlon style training at lunch I did a 10mi out/back on the road bike as part of the workout. Mostly so-so country road pavement with some bumpy junk. 24.3mph, 250w,...

With CdA testing, overstating a high CRR is one of the number one reasons people publish overly low CdA's. This is a pretty accepted conclusion in multiple sensor/aero/tunnel topics across both...

Plugging their stuff into aeroweenie necessitated a cda of .380 unless I made the weight pretty high with a crr of .004.

Stop pretending to know what you're talking about. You don't own the equipment to measure it nor have you gone to a tunnel.

To get that for their flat loop on the aeroweenie calculator I had to put in the highest recommended value for a CdA for a road rider. Around 0.400. Which is what I said above in an earlier post. ...

Their loop had zero elevation, it was an outdoor run/bike fitness track. The Strava elevation profile is about 4 posts above. Your loop there got nearly 1000ft in 30mi. A bit different. And, you...

To try to add something to this, I personally feel your airspeed and current power output matter with the inertia part on the flats. It's a lot easier if you've got a false flat downhill putting out...

I tried to read that, and despite a few good tidbits some was word salad.

This below means he doesn't understand in the article how hip angle affects power output between the two riding positions...

Thanks for the reply.

Look at the HR avg listed for your 220w part there and then the 260w part. The one for 220w is higher. This doesn't make sense physiologically for a 40w difference. The...

Kinda my point, even if we don't agree on the inputs to the calculators. We don't know his CRR or CdA. And 1.22 air density is pea soup.

Changing either just a bit would provide enough...

The one you posted has zero input for your CdA guess which is the largest influencer on power demands at a speed like 22mph.

The one you posted makes gross assumptions about CdA based on selecting...

You'd have to have a God awful CdA and CRR combo to only go 22mph on 240w on a flat road. Like, you'd need to be up on a mountain bike or Dutch with Gatorskins or knobbies.

So, the physics is off...
