# Halkyon Train's running profile for BRouter (ADR 0030, D44): BRouter has
# none for running, its hiking profiles sending runners up steps and rough
# paths, its cycling ones off footpaths. Paths, footways, tracks and quiet
# streets first, any surface; big roads only where nothing else goes, steps
# and scrambles avoided, motorways never. Written on BRouter's `shortest.brf`
# (its access rules and its voice hints' classifiers kept), 28 Oct 2026; not
# yet tried on a BRouter: the costs are a first guess, to be tuned on runs.
