20kms each way through Geneva, along the lake and up to near the Airport. Lovely in Spring, too hot in Summer, challenging in winter but toughens me up! It made me a bit tired at first but now my base fitness is so much better and I can feel the benefit when I ride for fun. 17 miles is doable, get some good skinny tyres on and go for it.
Ad yes headwinds on the way home are the worst, there is a strong winter wind call the Bees that blows from the East in winter, sometimes its been really strong and has been down to -20 windchill. I feel pretty Grrr! after riding back in that in snow.
