Start the day off right and join me for a slow morning run.

Running outside and in a slow pace has an energizing effect, helps to burn fat and to boost your immune system. Taking care of our health is so important, especially now.

This group class is suitable for new runners, pregnant women, new moms as well as non-moms. For all ladies who want to run, but slowly, and meet like minded women. 

We run at a slow pace, in the so called aerobic zone, at 50-70% of our maximum heart rate, and no more than 5km. 

A morning run is a positive, healthy start of the day!

“Marjolein is genuinely interested in helping people. She has a strong passion for what she does, which really helped to motivate me to keep going. Her program was very well structured and she takes time to understand what motivates people and how she can support you in reaching your goals. Marjolein has a big heart and I am very thankful for all the trainings and getting to know her. Keep it up Marjolein!”


“Wat was dat een zalige start van de ochtend! Dit wil ik opnieuw…liefst 3x per week 😁 een echte aanrader!”


I absolutely love my Slowmo(m) Morning Runs with Marjolein! Within a couple of months I went from hardly any exercise after having my kids to running twice a week – often not even that Slowmo anymore;) Not only is Marjolein a joy to be around and run with together, she is incredibly knowledgeable about how the body works and how you can set yourself up to enjoy running (again) and get the most out of it. During the runs, she gives so much valuable information about the body and running ’technicalities’, in a way that you can easily implement yourself and go from running once a week to adding two more runs by yourself every week. I highly recommend Marjolein!
