Great question. Keeping the body fueled with the CORRECT amount of carbs and proteins and keeping as close to hydrated as possible. Using supplements from Thorne to ensure that our body is getting the appropriate levels of vitamins and minerals along with each of our athletes being on different protocols designed specifically for their body based on their blood, sleep, gut, and stress testing. Sleep is going to be very hard to fully achieve and with 184 miles of running in 7 days from mostly non-runners, what could possibly go wrong? Antarctica could and should be in the negative. It will be closing their summer so we pray it stays around zero degrees.
