The first 12 hours in an adventure race is for me the worst, it is going a bit too fast and all the teams including us are a bit stressed. It is so much nicer the longer the race is going on. For me the challenge is the mental to make the team work together and be able to take good decisions even if you are physically tired and are very sleep deprivated. During a race that is 5 days we sleep about 8 hours all together if everything goes well.
