presumably if you skate 27 hours a day, and we go for 10 days, you will end up having to keep skating by yourself for 30 hours, to make up the lost time, i don’t if hans would close the rink for one person.
Also I think if you had fitness you could skate that long, if you were coming from little fitness it wouldn’t aide your fitness it would literal kill you, giving you zero fitness, so unless you had negative fitness before hand, it would hamper fitness
