Boulder century out & back ride — 101.85 mi
A hundred miles of paved road heading out and back, with about 2,636 ft of climbing spread across the day. You're looking at roughly seven hours in the saddle if you keep a steady pace, and you'll hit some regular traffic on the way out and back. One long push or split it across two relaxed days.
Boulder century loop ride — 108.25 mi
All paved and just over 108 miles with about 3,235 ft of climbing spread across the day, so nothing too steep but plenty of work. You'll catch some traffic on connecting roads, but mostly you're on quieter pavement making a big loop. At seven-plus hours of riding, you can take this as one long push or split it into two easier days.
