Self-propelled travel is used to commute short distances or even for much longer distances such as bicycle touring. It involves a conscious decision made by people who realize that self-propelled travel is environmentally sound, the ideal mode of transportation, and that it enhances quality of life at the same time.
Self-propulsion has been adopted by some adventurers as the new era of real adventure and exploring. A growing number of outdoor enthusiasts, such as the late Goran Kropp, Tim Harvey, and Colin Angus have achieved major feats entirely by self-propulsion. In 1995, Goran Kropp cycled from Sweden to Mount Everest base camp from which he climbed Everest. He then returned home on bicycle.
For some, the technological advancements of the present day are undermining challenge, comparing a helicopter ride to the top of a peak to that of getting to that same peak under one's own power. For this, advocates of self-propelled travel can be likened to luddites.
Critics of such hard-line definitions suggest a double standard is placed on the use of such apparatus. Other critics question using tailwinds or drafting techniques when cycling and suggest that only travel by foot or swimming qualifies.
