This is my Grand Canyon Rim to Rim hike in 1 day. In October 2022, I hiked the Grand Canyon R2R in one day. I took the Trans Canyon shuttle, camped for a night, then carried everything from the North Rim to the South Rim. I realized, I was the only R2R hiker that was carrying my camping gear across the canyon. Everyone else had day packs. So I would NOT recommend carrying a pack over 10 pounds through the Grand Canyon from Rim 2 Rim in one day unless you are experienced in 20+ miles per day carrying over 10lbs.
