A powerful combination of two-colour imaging in vivo, Fourier-filtered kymography and simulations provides a high-resolution view of kinesin-2 transport dynamics in cilia. This study reveals heterotrimeric kinesin-II as an 'obstacle-course runner' and homodimeric OSM-3 (KIF17) as a 'long-distance runner', and elucidates the 'baton handoff' between these two kinesin-2 motors on the microtubule track.
