Two weeks ago, my brother André and I decided to run the 10 km at the Haarlemmermeer Marathon on 2 September together. So this means that I need to make sure that by that time I am able to run those 10 km. So far I have only run 5 km. Yesterday I run for more than 40 minutes. I didn’t measure exact time or distance. This was just to get used to running longer. I will start to worry about distance and time later.
