For many people the thought of raising their oxygen levels for a marathon distance of 26.2 miles is enough to send their jaws gawping.
So why on earth would anyone set out to cover double or triple that distance when marathon running has enough esteem attached to it?
Well adventurer and ultrarunner Mike Buss explains that it is about sheer determination, as well as charitable giving.
He said on his website: "Ultra running has been around for some time but lately became the latest trend for normal people to take up as a challenge for charity or personals goals after maybe running a traditional marathon."
It seems for some, running more than two dozen miles simply isn't enough to fulfil their sporting ambitions.
Typical distances associated with ultrarunning include 50 or 100 miles and 50 or 100 kilometres, which are completed over a duration of between 24 hours and multi-day events.
So if you're up for the challenge next season, why not choose from more than 1,000 ultra races taking place across the globe in 2013?
