what do you say about RAAM?
RAAM-Race across america from Oceanside, CA to Atlantic city, NJ

3042.8 miles which the best riders make it in 8 day and 9-10 hours
this is probably the most extreme competition on earth, mainly because of deficiency of sleep. I dont know how I would function if I slept 12 hours in 8 day (ok, some sleep more, but........).
i probably wouldn't be able to keep my eyes open,not to ride a bicycle.

two women are also in competition this year (last year was just one) , good luck for both of then

all who finish the race in 12 days (time limit) is a hero, and olso a little crazy (not just because hallucinations)

Good luck for everyone
