Boise century out & back ride — 123.97 mi
You're looking at a solid 124-mile out-and-back on all pavement with about 1,216 ft of climbing spread across the ride — perfect for a long distance day on quiet roads where traffic barely registers. Head out and return the same way, enjoying nearly car-free riding the whole time. Expect to be out there for a good eight hours plus.
Boise century loop ride — 101.21 mi
This is a solid 101-mile paved loop with about 1,500 feet of climbing spread across the route, so you'll be rolling steady rather than facing any single big push. You'll spend a fair amount of time on busier roads to string it together, but the distance and consistent elevation keep it interesting. Plan for six-plus hours in the saddle.
