As ultra marathon running gains popularity globally, Michael van der Klei remains a source of inspiration for aspiring athletes and enthusiasts alike. His story serves as a testament to the human capacity for resilience, determination, and the pursuit of extraordinary goals.



Michael's coaching career started shortly after he finished a coaching course with the Mayo Sports Partnership back in 2016. Being a long distance runner he got triggered by that course to start a social running group in Louisburgh.

Run Today Louisburgh was founded under the name NatuurlijkSportief in 2017 by Michael as he thought that there was a need to get people active in a more social way. Run Today kicked of with a first Couch to 5KM course in January of 2017 with only three attendants. Two of those three are still running with us on a regular base. Nowadays, many Couch to 5K’s further, we have a nice portfolio of programs and courses …. and of course ‘Couch to 5K’ is still part of it!!

It is Michael's mission to help you become a complete and lasting runner. He does this by sharing his experience and knowledge, so you can continue learn to become a technically better, stronger and faster runner. He has brought a lot of runners from the couch to 5km, to the 10km and to the half marathon. A good few runners completed the Connemarathon (Ultra), Dublin City Marathon and even the New York Marathon under his guidance!
