I've finished the famous 4Daagse in the military category (4x40km with 10kg; although the weight requirement was lifted at the last day due to heat) for the third time.
Along the way there was a lot of time to reflect. Like 'why the hell am I doing this for the third time?' But when you reach the goal it just feels amazing and you want to do it again! And of course this would not have possible without a team who walked along and helped wach other when someone had a bad moment.
Keep following your goals. Keep on marching. You never walk alone!
