+1 for Google Earth, it's arguably better than a measuring wheel if you're good at it.

GPS watch. Run it 5 times, mark each time with chalk. Take the average of the 5 marks. It can't be more than 1-2m off if you do it that way. That is close enough.

They say Patrick Mahomes can throw the ball a mile, so just invite him over and go deep.
Draw a line on the road. Get in your car and start your Garmin on 0.00. Drive to 1.00. Mark the road. Drive back to the beginning and do it twice more. It will be a slightly different spot each time. Take the point halfway between the two outliers and you'll be very close.
That's the quick and dirty way.
You can get a relatively accurate measurement using Google Earth if the road is straight, flat and exposed (image not obstructed by trees or buildings).
Some additional suggestions:
1. Don't use miles as units. Use feet (5280) or meters (1609.344).
2. As previously mentioned, zoom in and find a landmark in the road to measure from - stop lines, pedestrian crossings, etc.
3. You might want to consider adding 0.1% (5.28 feet or 1.61 meters). This is the "short course prevention factor" that is added to all road course measurements.
4. Measure it a few times and take the average.
If there are trees obstructing the view, you could use "Historical Imagery". It's on the drop down menu - "View". This will enable you to view previous images of the area - some without leaves on the trees!
Google earth path measure is crazy accurate. I've measured several outdoor tracks (400m) with it just to verify and its always within .5 meters.
Google Maps displayed distances when you searched for directions, but it would only tell you the distance along the planned route — not the exact distance between the starting and final destinations. For example, you might search for directions to a restaurant that's exactly 3 miles away (if you draw a straight line), but the route Google provides for driving directions might actually be 3.5 miles.

This is what I was going to say. Measuring wheel.
I needed a exact measurement for a 1k course, so l went to Home Depot and bought this wheel, the Cresent Lufkin. Although it's in feet, all you have to do is Google and convert from feet to meters. So l marked off a course marking every 100 meters, except at the 1/4 and 1/2 mile, as l marked the 1/4 and 1/2 mile instead off 800 and 400. This wheel is very stable and accurate because it has gear drive. It saves time on going to the track and it's also on the surface l race on(the road).

You’ve predetermined that you are going to measure one mile, so the average of three measurements will, by definition, be one mile. What is the point of averaging three measurements if you’ve already determined what the average will be?

That's only accurate if you measure on the line of running, 20 to 30cm outside the painted line, depending on the type of track. The painted line is 398.xx meters.

why the need to push the bicycle ?
could this be done by riding it ?
Yes. You could ride the bike, but I didn't want to damage the track or get kicked out if anyone saw me riding around the track. I figured I could talk my way out of pushing it around the track, but not riding it around the track.
Yes, pushing it on the road would be more accurate---but just how much difference would it make?
Lastly riding one's bike around a track and staying the exact distance from the inside lane would be EXTREMELY HARD TO DO!
If you are going to do the wheel, how about also using a GPS watch just to see the difference?

Back in the 80's I measured a straight and flat mile on a country road so that I could train doing straight intervals while preparing for a one mile road race. Since I lived in the country near this road I figured it would save me driving into town to use the track.
First I measured a piece of rope 110 yards long and with the help from a friend we measured it 1/16 of a mile at a time. We marked every 220 yards with spray paint. It turned out pretty good.
One week later they redid the road with tar and pea gravel.
Oh man...
Don't forget about the extra distance from the curve of the earth
Get a 12 inch ruler, measure it 5280 times back to back and you should get your mile.
