Mudslide Obstacle Trail Run

Mudslide postponed to August or Sept. 2020

Looks like we are going to have to postpone the Mudslide to summer or fall, 2020, date to be announced soon. Until then, do your pushups, crunches and then get outside and do some solitary training runs! Sign up now with no risk. Once the date is announced, if you can't run on the new date we will refund your entry fee.

Very muddy woman runnerThe Holiday Valley Mudslide is a mudrun that's really, really FUN. Yes, you'll get muddy, yes there is running, yes there are lots of obstacles but NO fire, NO barbed wire and NO electric shocks! We plan to offer a short and long course option with the start at Spruce Lake on top of the mountain. More info to come. Be sure to join us this summer, 2020 for the ninth annual Mudslide!

A portion of the proceeds will benefit Jim Kelly’s Hunter's Hope Foundation, a non-profit organization committed to giving hope through education and awareness, research, and family care for Krabbe, Leukodystrophies, and Newborn Screening.
