there is a Mountain Bike trail network here that appears on Google Maps but is not updated in OSM - see https://www.mtbproject.com/directory/8024474/defeated-creek-park
https://www.trailforks.com/region/defeated-creek-park-15968/

new pump track has been constructed here, as well as an expansion to the playground

this road doesn't seem to be continuous on certain routing services (graph hopper). not sure what is going on
