Hello, nice to see you drop by :-)

According to Google Maps, it's 11.6 km from the city center. The way there should be slightly downhill given that the river flows in that direction, I guess, but you can ask Starbug for more details.

Don't worry about being slow, I wen to Thun last Friday and I am about the slowest cyclist on the road. Bern surroundings are mostly flat as far as I can tell...

Cheers,
Carlos
