New hill for me today, Cnoc Choinnich, also took in The Brack, both Corbetts, CC only promoted to one in 2016. Started at the Ardgarten car park, 3 miles on road and forest rack to start, climbing up through Coilessan glen, from the high point hang a left, faint paths over moorland then a steepish climb through a wet gulley onto the ridge with a short run to the top, good views down the Clyde estuary and across to the rest of the Arrochar Alps, a bit of cloud blew in as we reached the top. Back down and across Coilessan glen and a path up The Brack, there's a few different paths, picked a better one than usual, took us all the way to the top. Took the race route down, taking our time on the steep, twisty, rocky descent. Finished with a mile or so on forest tracks back to Ardgarten.
