Those are mountain bike specific, with mtb specific features. We are more general road/adventure riding, though you can of course use our service to plan a mountain bike ride. If you want to go to a trail system with a network of 1-5 mile trail sections, and just want to show up and link stuff together, mtb project and trailforks have a better feature set. If you want to go on a 30-40 mile mtb ride on a trail and get navigation (not dynamically linking together individual trail sections), then we work pretty well.
