GitSum Adventures runs a weekly offroad calendar with something for whatever mood you're in — Scenic if you want to spin and look around, Challenge if you want to work for it, or EPIC if you need to remind yourself what suffering feels like. Suspension isn't required, so your gravel rig or sturdy hardtail is already the right bike.
Rides rotate between in-town Albuquerque routes and out-of-town escapes, keeping the schedule fresh week to week. Lengths and fitness demands vary with the tier, so there's no reason to sit one out just because you're not feeling heroic that day.
