There is a useful but unmarked path from Queen's Road to Richmond Park and through to Sheen. It is used by pedestrians and cyclists & I have never seen it on any map! From Lower Grove Road, it takes you to the park via Bog Gate, or Sheen via Sheen Common.
If it were better marked on maps, better maintained & wider in places, it could form a useful section of Richmond's (paved, segregated, Dutch style?) cycling network.
