Beside me, who else can know their ride data without looking?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I can, almost without fail know the following without looking at my Garmin:

MPH: to within .5
Cadence: to within 4 rpms.
Heart Rate: To within 5bpm.
Incline / Decline: To within .5%

Only times I'm way off or can't verify is during an all out sprint.

I don't have a power meter, but I assume eventually I'd get that too.

This is probably pretty common?

I think so for folks that ride a lot. Traffic cops can guess your speed pretty close too.

Definitely not my HR which varies dramatically between the morning and evening and during the course of a ride for a given RPE. Power also feels quite different after a day off vs at the end of 5 straight days of riding.

Speed within discipline (mtb, road, etc), cadence, and heart rate are all pretty constant in terms of averages at the end of a ride. I could tell you before, during, or after what it's going to end up being.

Not having a HR monitor on me (gasp!) nor a computer (double gasp!!) to give me immediate feedback and develop that sense, I could probably tell you my HR to within 5 beats and my current speed with 5km/h. That's not much use, I know, but neither is having a HR monitor and a computer on my bike.

When I was running a lot I could tell my pace to within 3-5 seconds per mile, as well as the over pace of the entire run. Now I'm like 20 seconds off, and sometimes even run without wearing any electronic. Triple gasp!!!

I bought heat rate sensor and cadence and it turns out that after I warm up my cadence and heart rate end up almost exactly were they are suppose to be. Nice to visually see it though.

For normal solo rides you can get a feel for what your numbers should be, but there can be a lot of variability on how you feel, whether riding into a strong headwind, riding with a group, affected by allergies, etc. If you're doing intervals and training in specific zones, it is very difficult to estimate what zone you're in without a bike computer.

Pretty much the same except for grades, we being fairly grades out here in flatlandia. It's why I stopped using a computer. Why bother looking at what I know.

No. Until I download the PM I don't know really how well (work) I have done. The really crappy days with a headwind for example can result in really good numbers. I have 6 yrs of power data to compare.
