Coach O'Brien Memorial 5K St. Patrick's Day Run

Join us as we bring back our 5K St. Patrick's Day Run for the second time in memory of Coach Mike O'Brien on our USATF-Certified course (Course certification # is NJ24014JLW).

Mike O’Brien was a beloved cross-country and track coach at Morris Catholic for 25 years. Additionally, he started the original Morris Catholic St. Patrick’s day 5k back in 2012. He really enjoyed the MC 5K and seeing/catching up with all the alumni as well as local runners that came to run.  We are so glad to be able to bring this race back in his name!

IT IS NOW A LIVE RACE. Get out into the fresh air and join us on Saturday 3/15/2025 at 9 am at Morris Catholic High School in Denville NJ.  SHIRT QUANTITIES ARE LIMITED; REGISTER BY FEBRUARY 15TH TO BE GUARANTEED A SHIRT!

The race proceeds will benefit the Morris Catholic High School scholarship and athletic programs as well as the Denville Public Assistance Fund!

Did you know that Morris Catholic is a co-educational college preparatory school in Northern NJ founded in 1957? Morris Catholic was designed to serve students in Morris County from a perspective of Catholic values. With an average enrollment under 500 students, Morris Catholic is considered to be the right size for a student who wants to find a community that is authentically caring and lands students in the best colleges in the country.  One of Morris Catholic’s goals is to keep its tuition within reach of all families. Therefore, it relies on various fund raising activities such as this race, to enhance the students’ high school experience and to provide scholarships to those who require financial assistance.

As Morris Catholic is located in Denville, NJ, it is only fitting that the proceeds of the race are shared with the Denville Public Assistance Fund, to give back to this wonderful community!

A good run for a good cause? Let's do it!

May the luck of the Irish give us a sunny day; but the race runs on Rain or Shine!
