You need an extra motivation to lace your shoes and go outdors for a run, now that day's are shorter and the weater chilly. Why not join a group to run? We run along the lake on evenings and werkend days, starting from Lausanne Vidy. Runs are for about 1hour and 10-12km, or as long as you wish. There is no coach or trainer. Everybody runs on his own responsibility, but with the extra motivation of beeing part of a group.
