My Journey to 500K: Running Challenges and Consistency
Ever since I started running again in 2020 during the Covid shut down I have been struggling to keep the momentum going over the year. I had set my yearly target in Strava at 500k but there always seemed to be something to make me ‘stumble’ and stop running for a while. So last year I set myself a target to run 55 times in the timespan of a year (birthday to birthday) to introduce some consistency in my running frequency. I did reach that target but without running 500k in that timespan. So for the next year I set…

Nickel and Dimed. On (not) getting by in America, Barbara Ehrenreich (ISBN 9780805063899, Henry Holt & Company)

Traveling Long Distances with Electric Cars: My Experience
Last year we had our first experience with going on vacation with our electric car, an Audi Q4 Eton. We didn’t travel too far, maximum 550km and drove relatively slowly on the highways in France. The experience with finding charging stations along the way and on our destination was quite positive and this year we took a ‘normal’ trip in the sense that we didn’t limit our destination because we were driving an electric car. We went to Croatia and split the 15OOkm trip into parts as usual so as not to spend a whole day in the car. Again,…

Discover Belgium Peak Beer: A Hidden Gem for the Lazy Casual Hikers
When we recently went for a couple of walks around Herresbach we stopped at Belgium Peak Beer on our way back home for lunch. The original plan was to go for lunch around Longfaye as that is were our walk started and ended but it was on a public holiday and the places we planned to go to was closed. Google search came to the rescue and we picked Belgium Peak Beer as the alternative. Our walk was approximately 14km long trailing the border of the nature reserve. As it was not too long and we thought we would be…
