Approx 5.5 hours with stops from Aurillac take the N120
(Re signed as D1120 in places) through Argentat all the
way into and through Tulle to Seilhac where you pick up
the D940 all the way to Treignac and Riders Rest. -
You can get congestion on the N120 and Tulle can be
complicated uless you have satnav (which will try and
push you down small D roads such as the D44 after Tulle).
