We'll start and end by train, and this will be an all-day affair.
We start on an 8.01am Rodalies train from RENFE Plaza Catalunya to arrive to Vic at 9.20am.
We'll then follow this route: http://www.mapmyride.com/routes/view/304717413
This will take us out of Vic and pass through Folgueroles, turning through Tavernoles to go up to the west end of the Pantano de Sau where we'll briefly visit the Parador de Vic-Sau, then retrace our path back to Folgueroles, continuing around to the south side of the Pantano passing through Vilanova de Sau, around the east edge of the pantano to the north side, as far as the road will go. We retrace briefly, then turn up a tiny paved track to climb gently for 15km through Sant Joan de Fàbregas to reach Rupit. At Rupit we rejoin larger roads, the C-153 climbing briefly then starting a 13km descent back towards Vic, but turning off at Sant Martí Sescorts to cross the countryside to arrive at Torelló. (Curiously, this is the same destination which the next day's ride will reach, from the opposite side).
Pace will be intermediate, terrain will accumulate a goodly amount of climbing (MapMyRide says 1200m of climbing), but we won't attack any mountains. We'll stop for water, and probably once for a bocadito (most likely in Rupit), but this will be mostly to get some distance under our wheels, through amazingly beautiful countryside as I always try to do :-)
Trains return from Torelló at 15:15 (which we'll likely make, if the bocadito stop is quick and we don't have lunch at the end of the ride) and then at 17:26 and 18:34 (if we want to take more time / stop to eat).
