While it is not recommended to hike rim to rim in one day there are those that will hike rim to rim and then back in one day or even over multiple days. Either way takes some hiking/ultra running experience, months of preparation and training as well as a lot of grit and determination. This sticker is for you. Slap it on your water bottle or your car or wherever you want to commemoration your awesome achievement.
These stickers feature a special laminate that protects them from exposure to wind, rain and sunlight. You can even put them in your dishwasher and have them come out looking brand new!!!
