As we risk not having anyone around to do a run on the 21st, we'll have our Christmas r*n on the 14th instead.
BDR will set a most merry trail for runners and walkers. X-massy costume will be welcome ! A bag-car will be available near the station, follow the dots of flour.
How about a good fondue afterwards at the Café-du-midi, rue de Romont (near the station)?
The train from Bern leaves from 13:34. If you come by car, just make sure you there on time.
