We have a pretty decent number of routes. We're in a northern suburb of LA and our town has really nice bike paths.
From my house, it's maybe 1/8 mile to get on a bike path and from there I can reach the outskirts of town in most directions. Since we live in a valley, there's lots of climbing routes into the mountains.
We have maybe five long routes that we can do from town, in the 50 mile range/5000 ft climbing range, and I can leave from my front door. I can ride 100 miles out & back to Mt Wilson. I organized a 125 mile/11000 ft climbing ride from my house once, up and over the mountains into the San Fernando Valley then back up into the mountains in a giant loop which eventually wound up back home. If I wanted miles but less climbing, I could ride to Santa Barbara, around a hundred miles.
We have some good options for shorter routes too, maybe 4-5 nice scenic 20-30 mile rides.
Also decent stretches of roads to get interval workouts done as long as I head out before dawn when traffic is light.
Add in mountain biking and we've got huge options in town. If Im willing to throw the bike in the car, I have dozens more appealing options within a 60-90 min drive.
I was just thinking this morning when I was out doing a wee recovery ride on the bike paths how lucky I am. I took up cycling after we moved to this town and I saw all the nice bike paths. It's really a testament to infrastructure- how if a town builds it, they will come. And be healthier and happier to boot.
When y'all are done with down under, you can move to LA. Completely loopy place to live. Exasperating traffic. Expensive. Every cliche about it is completely correct. But the cycling is good.
