Each map is drawn to its own scale, north up; the dot is the start. Elevation is drawn to one scale on every card, coloured by slope as on the ride pages. Easiest first means the shortest estimated riding time at a sporty pace, which counts the climbing.

Rides are modelled from OpenStreetMap and terrain data and are not field-checked yet. Times here are estimates at a sporty pace. Catalogue access does not mean a ride fits your ability or available time. Low traffic stress includes quiet/shared streets, not just separated paths. Check current conditions before you go.
