I have a 1.8 mi loop from my door that I typically do 3 hard 2 easy then head out from there for other places. My subdivision is designed with a lot of loop options and doing 20 mi of various loops is easy. Probably the longest single loop would be about 5 mi.

In my area there is one four blocks area t hat if I ride the four streets in a box pattern it's exactly one kilometre per circuit. It's a great place for doing interval training. I can ride until I'm bushed and have less than a kilometre to ride to get home.

Cheers

Edit. What I like about that loop is that two of the streets are quite short and the other two are longer. The longer streets are fantastic for practicing sprints or for doing intervals . One of the longer streets is a very quiet residential street that i can go quite fast on with no worries about hitting any pedestrians.

Look up the one year mileage record a woman in Florida did a couple of years ago. 85,000 miles, all on the same approx. 7 mile loop. 232 miles a day avg, 33.5 laps per day, though she said she took at least a day off a week. YIKES!

When I rode centuries each month (CAM challenges!), in the summer, I'd do one big loop or out and back. But in the winter, I'd start with a short loop of 5 or 10 km and do that until the sun came up a bit and roads dried off a little. Then I'd do longer loops ... maybe 25 km a couple times, perhaps even a 50 km loop if the day was nice. Then I'd return to short loops as night fell again.

Did an hour and a half (30+ miles) on this little bitty loop of 1.05 miles on this ride:

I've actually done 40 miles on that loop before joining Strava (so I didn't record it). Those rides weren't as boring as it seems like they'd be because of focusing to keep 20 mph the whole time.

Here's a longer ride (with a few unplanned stops for chain trouble) on a more reasonable 8.73-mile loop - but it's still a fair number of loops:

My GF gave me the cold shoulder, so I spun my bicycle in a circle for 17 minutes.

My long rides are usually in the form of a loop to begin with. But last weekend it was 98.5 miles and vanity dictated I loop the neighborhood until it rolled over. (Besides, I also felt like I could keep going another 50; tired but comfortable.)
