I frequently create segments on routes that I (and/or my community members) run and cross country ski. Many of the routes I take on these runs are common to running and cross country skiing. They are also used by (mountain) bikers and walkers.
Instead of creating separate "run", "nordic ski", "bike" ... segments, it'd be great if the segments can be created from one activity (say, running) and be usable by other activity types (say, nordic ski, mountain bike, etc.).
