[HALO] How long would it take the average man to walk the length of The Ark (Installation 00), accounting for time needed to rest, eat, drink and perform other vital biological functions?
gpt
The Ark created rings of 10,000 km in diameter. 

So let's assume the ark is bigger since it has to make them. If Master Chief could walk at 8km/h then it would take him a minimum of 1250 hours. If we say he can walk for 16 hours straight at a constant pace, no running, then it would take him nearly 80 days. Minimum.
