2020 Registration Updates:


As we watch the COVID-19 pandemic unfold it’s hard to say what will happen over the next few months. The Carriboo Jack is slated for the weekend of September 11-13 of 2020, 6 months out from now, and we are confident in our ability to safely run the event during that time frame.

We are still planning on running the event according to schedule, but we will be postponing registration until things start to calm down. We will keep you updated on our plans for opening registration.

Safety is our #1 priority. We will be implementing a no-questions-asked refund policy for this year’s event once registration opens. As things progress over the next few months, rest assured that we’re going to make certain calls to keep you and everyone else safe.

We look forward to seeing all of you in the fall and in the meantime stay healthy!
