My commute used to be 6.7 kms each way for a total of 13.4 kms, and if I felt like it, I could extend the trip home. That commute was completely city riding, but for the most part the streets were fairly quiet. And that commute was almost entirely flat. I could take a different route home which would include an overpass ... and I did that fairly regularly to get some hill climbing in.
Now it appears that I will have a commute of 30 kms each way for a total of about 60 kms. The route is mainly in the country, which might be a nice change from city riding. It also appears that my commute will include at least 2 hills each way ... real hills, not just an overpass!
That's quite a different from what I was used to!!
But it makes me curious - what is your commute like? Length? City or country? Terrain?
