Rieda

Rieda is an AI route planner for cyclists. Tell it what you want in plain language — 37 miles from Boulder, a bit rolling, quiet roads — and it builds 20 loops, scores each on surface, traffic and climbing, and hands you the best three, back at your door. Ask for flatter, longer, or as gravel and it replans while you talk. Untagged road counts as risk, not tarmac: a road ride goes around it, a gravel ride goes looking for it. Road, gravel and MTB. Free for ten routes a month.
