A question just for fun.
I’m in Kansas (insert flat land joke here).
Where state do you live in and if you go out your door and do a 20 mile loop, how much ascent do you average?
I know geography varies a lot within any given state. Like I said, the question is just for fun.
Socal. I can do a 60 mile loop with 500 ft total or choose a different route with 500-750 ft every 10 miles. All routes start from home, no driving required, and no hill repeats.
I’m in NJ. Checking my latest rides from my door, I’ve got 1447ft in 27 mi, 955 ft in 18.15 mi, 837 ft in 13.4 mi, and 1339 feet in 16 mi.
Rides not from my door but still in NJ: 1033 ft in 28.3 miles (much of this through the area called Great Swamp, so flatter is expected) and 2585 ft in 31 mi.
In one direction it would be <500 feet. In another about 2000
To the west my out-the-door route starts at 60 feet above sea level (asl) and descends to 9 feet asl, and then back home. Plus 2 freeway and 1 train overpass. Garmin barometer usually logs 200-ish feet of “climbing” and here is WKO chart which makes it look dramatic 
but look at elevation above sea level on the left hand axis:
The only perceptible elevation changes are the (in order) train overpass, freeway overpass, and pedestrian freeway overpass. It actually feels like this:

HOWEVER, if I head east, within 1 hour its a straight climb up to Lake Tahoe and about ~15,000’ / 4600m of climbing.
or if you want a flatter challenge to the Pacific ocean, you can avoid the HC climbs and take the “flat” route to San Francisco
either east or west there are not-so-flat epic all-day ride options!
If Kansas is flat you get to take advantage of ‘windervals’ for training right?
I’ll preface this with… The world is flat according to some.
Depending on the road route I take the elevation gain can be as little as 55’ per mile or as much as 120’ per mile or in other terms, for a Century it could be a total of 5500’ or 12,000’.
I did a local Century a few years back and there was a group that came out from Delaware because they wanted to try some “hills”. On the first ‘climb’ when I was with them they grumbled something like - this is bs to which I replied; no worries, it levels of to 8% in a quarter mile.
At 105 miles and 12,700’ of gain they got their wish although I never saw them after the event to ask if they enjoyed it.
But again, the world is flat.
I live on the extreme west side of the Denver metro, as in it starts heading up into the mountains literally out my back door.
If I go out my door and go right I head into a relatively flat state park and a 20 mile loops is ~800ft of elevation.
If I go out and go left then it’s just a matter of how long you want to climb for. I have a relatively straightforward route all the way up to 14K ft of elevation but that’s obviously insanity and only do that maybe once a year. My normal O&B road route is
That’s over 20 miles. My MTB routes are all around 3-3.5K ft elevation for 20 miles.
Between 55 and 60 feet per mile here in the hill county of texas.
I’m waiting for @Majoeric to turn up and show off with his 89ft century.
Portland area here. I can average 80-100 feet of climbing per mile pretty easily
Haha… I don’t think it’s that low? I usually avg around 1-2 ft a mile!
Here’s a typical 100 mile ride…
Found it: 
It stuck in my mind because it was so incredible.
Where I am, as flat ride probably has about 500ft per 20 miles.
I checked the stats from my most regular routes during the past few years and it seems the accumulated ascent is around 500 meters for a ride of around 60 kms. So less than a kilometer for a 100 km ride. The ascent seems to be approximately the same for my road rides and gravel rides.
This out my parents door, DnR towpath at the New Brunswick end.
My dad joined a cycling club in a hillier area just to get some climbing rides.
Garmin always messed up the elevation at my old house, also half mile from dropping onto a canal towpath (C&O), start and finish never same and out and back not even remotely symmetrical.
Can see “mountains” outside new house but haven’t done any good rides yet.
Haha… awesome! I basically live on the outskirts of the Everglades and we have zero hills. Only elevation gain for me is an overpass or bridge. It definitely has its pros and cons.
