You MUST have a plan for sleeping set up for all your team members. Some team members slept in our van, some on a football field ground and the ground of a gym floor with the yoga mat, small blanket and pillow that you bring. Even though the gym ground doesn't sound too bad there are people always coming in and out of this gym since everyone finishes at different times all night. I would recommend bringing ear plugs and a thick sleeping bag or yoga mat and extra blankets since it can get really cold even indoors. And taking naps when you can to get extra sleep in since our team finished later we got to lay down for not even 5 hours. I really enjoyed the teams who cheered for everyone and keep positive vibes going even though we knew everyone was tired. The end of the race is also very cool to watch all the teams come running in together. There aren't very many water stations and quite a bit of driving in between to get to the next relay zone and that can be a bit confusing at times. Make sure to bring plenty of water, snacks and ibuprofen. This races really pushes your limits based on the amount of miles you run and how much sleep you can get in at night and who you are running it with.
