New Location this Year- Holiday Mountain Ski Area, 99 Holiday Mt. Rd. (same Rock Hill Exit)

Thank You To Our Participants, Volunteers, Sponsors & Donors

Thank you to everyone who participated, volunteered, sponsored and donated to the 32nd annual R4 - and the 1st at Holiday Mountain.

Thank you to the amazing staff at Holiday Mountain that worked so hard to get the site ready, amidst their own ongoing renovation.

The event was a great success for the charities we benefit. We will clear @100,000.00! We had a beautiful day at an amazing venue, with good feedback on the new course and the volunteers who supported it.

We apologize to anyone who waited too long to get in or who was prevented from going out while the race was in session. There are logistical issues that we will solve related to traffic, parking, and the ability to leave the venue while the runners and walkers are still on course.

We are already working on solutions to address these issues for next year in an effort to enhance your experience, while prioritizing safety.

Thank you all for choosing to matter.

- Suzy Loughlin, Race Director

The R4 has moved to Holiday Mountain Ski Area.
99 Holiday Mt. Road (Exit 109 or 107 East; Exit 108 West).

We have a new USTAF Certified Course. — Runners, you will love that it is fast and flat, meandering along side the Neversink River. The scenery won’t disappoint. Walkers, you will love it because you will get to see your friends and family coming back towards you and be able to cheer them on. And remember- this is for charity. This event benefits patients diagnosed with blood cancer and other acute catastrophic illnesses. By participating, you are choosing to matter!

Course Record - 2024:

  • Female - Skylar Musa, Grahamsville, NY, TIME: 17:33

  • Male - Vann Moffett, Niantic, CT, TIME: 15:05

Founded in 1993 by Suzy Rhulen Loughlin and a team of dedicated volunteers, the R4 first benefitted the American Heart Association. The battle to cure leukemia became a personal one for Suzy and her family, when in 1998, her father, Walter Rhulen, died of leukemia. Walter was a dedicated runner, committed to the health of his community. His loss inspired the R4 alliance with the Leukemia & Lymphoma Society.

In 2013, another tragedy resulted in the death of Suzy’s son Trevor, 21. The Trevor Loughlin Foundation, fueled by the force of a parent who wants her child to be remembered, and the friends and family who support her and the TLF mission, raises funds and awards grants to patients fighting blood cancer and other acute catastrophic illnesses.
