Today, the CMRR, now renamed "Catskill Mountain 100K Road Race & Relay", is more than just a relay. It is still the only 100K relay race in the northeast, and the oldest relay of any distance in the region. It is also now the most challenging and scenic 100K road ultramarathon east of the Mississippi River. Ultrarunners will revel in the challenge of the course, with many gut-busting hills, and a changing landscape that will evoke wonder in the eyes and imagination of the intrepid distance runner.
