I'll swap you a few hills for some flats!
Even our house is buried in the side of a hill at 278m above sea level - at least we are safe from rising sea levels!
All my routes start either going further up the hill on the road at the back of the house - not good as my legs are not keen. Or down the rough track at the front of the house which is nice but then I have to usually grind back up it at the end of my ride.
To make a circle of the down and up bit makes for a long ride which would almost certainly exceed my boredom threshold!
