I don't drive so I ride when going on errands, shopping and going to the swimming pool. However, none of these trips are particularly long and even when they add up in one day to 15-25 miles or so they're usually broken up with stops along the way. I probably need to push myself a bit more on these trips.

As for zig-zagging, well the first graph is when I zig-zag. The big hill I have to go up is North but the roads going off it to the East and West go up hills on either side too. I dread it! but at least it's over near the start.
