Rim-to-Rim-to-Rim in the Grand Canyon

This run is an extreme adventure and requires lots of planning and training. The risk for injury or heat related illness is high, so take precautions and don't run alone. Group sizes of 12-30 require a $175 permit from the NPS. These trails are popular with runners, hikers, and backpackers; please be respectful on the trail.

There are a few ways to run R2R2R, with the popular option being down South Kaibab, up North Kaibab, and up Bright Angel on the return. The distance for this route is slightly longer than returning to the South Kaibab TH. There is no vehicle access to the South Kaibab TH. It's a 2.4 mile run from the visitor center or a 10-minute shuttle ride. The shuttle leaves at 4:30 am and every half hour until 6am, and every 15 min after that until 1 hour after sunset. Average time to complete R2R2R is 13-15 hours. There is also a supply mule train that comes up South Kaibab in the morning, it usually starts between 8-11 and shouldn't impact early starters.

There are 3 year-round water locations: Phantom Ranch, Pump House and Indian Gardens as well as water at the South Rim trailheads. The rest are all seasonal with water usually available on the North Rim by May 15 (or when the rim is open to vehicle travel). As a general rule, the ideal times to run R2R2R are early April to mid-May, and late September to late October. Temperatures during this time can approach freezing at the rims and over 110˚F in the canyon. You can escape this heat in the winter but do not risk running on snowy days. Summer is not an option due to the extreme heat throughout the day.

Other guidelines and info:

• The Grand Canyon ecosystem is stark, bountiful, and fragile at the same time. Please respect the trails and follow leave-no-trace guidelines.
• If you have a large group, split into smaller sub-groups to limit trail impact.
• Mule trains have the right of way.
• Communicate to other trail users as you approach them to minimize surprises.
• Down South Kaibab - Up Bright Angel Trail (45 Miles)

This run can be a life-changing event and if you're properly prepared, incredibly fun!
