Participating in a Rim-to-Rim-to-Rim (R2R2R) run in the Grand Canyon is a self-organized, self-supported endeavor. This is not a professionally organized event; there are no aid stations, crew support, or designated medical facilities along the route. The only access for medical and rescue services is at the canyon rims or by helicopter. This significantly increases the risk compared to organized ultramarathon events which have frequent aid stations and medical support.

The content provided on this website is for informational purposes only, based on personal experiences and publicly available information. It is not intended as exhaustive guidance nor should it be construed as professional advice.

The National Park Service does not support this run and there are many signs warning about the dangers of descending to the river and back in one day. In fact, the NPS recommends a trip of 3-4 days for R2R2R.

By choosing to run R2R2R, you acknowledge and accept full responsibility for your decisions, preparation, and actions before, during, and after the run. It is imperative that you evaluate your physical condition, prepare adequately, and consider consulting a healthcare provider before embarking on this challenge. Respect for the park’s regulations, the natural environment, and commitment to leaving no trace should guide your preparations and actions.
Everyone who starts this run is making their own decisions and understands they need to be self supported and have adequately prepared for the run.

If you're ready for this challenge and have prepared accordingly, you're in for an unforgettable experience. Proceed with respect for nature, your fellow trail users, and yourself. Remember: Down is optional. Up is Mandatory.
