Was that and also that I hit the wall hard during the marathon. Didn't get enough liquid and energy, so got cramps already at 25km.
Mentally it was draining and left me in a state that didn't motivate me to train. But now its fun to run again!

Managed to get a time of 4.10 ish, but had a goal to hit it under 4h. My speed until the I hit the wall had got me around 3:30 😅
