The need for speed is seated somewhere deep within the human psyche – maybe it's those millenia we spent chasing down our meals – and as such, it should be no surprise that we can make a race out of well, anything. Someone always wants to be fastest, whether it's by foot or flight.
As such, we've rounded up seven of the world's fastest human beings in endeavours that don't necessitate fuel, wheels or wings. (OK, one has fuel – and wings. But it's worth it. Trust us.)
1. Antoine Albeau, windsurfer
Speed: 52.05 knots
Why it's tough: Gale-force winds required
How fast is 52 knots? Approaching 100km/h. That's the speed Antoine Albeau hits on his windsurfer, powered only by the nuclear off-shore winds of Namibia's Skeleton Coast. His custom-built board and rig is tuned specifically for speed in one direction. The biggest challenge in hitting that speed? Controlling the board in chop – that's why they seek off-shore winds, where chop has little chance to build.
2. Kilian Jornet, mountain runner
Sport: Mountain running
Speed: Faster than everyone else
Why it's tough: Training, training, training
To call Kilian Jornet super-human is somewhat misleading – he's a human, he just trains harder (and higher) than anyone else. The Spanish mountain goat (he was raised in a hut at 2,000m) is the world's best trail runner, regularly racking up wins in off-road ultras when he's not bagging peaks in his Summits of my Life project – which has him seeking to set FKT ascents on the seven summits.
3. Danyil Boldyrev, speed climbing
Sport: Speed climbing
Speed: 7 seconds/15m
Unique challenge: Slip? Fall...
Speed climbing is a slightly obscure sub-set of competitive climbing that focuses more on power and pace than technique. Harnessed into an autobelay, competitors literally leap, side-by-side, up two identical routes. First one to the slap the buzzer wins. Danyil Boldyrev is currently the fastest guy in the world.

4. Alex Caizergues, kiteboarding
Speed: 56.65 knots
Unique challenge: Crash potential very high
Alex Caizergues has long been the king of speed when it comes to kiteboarding.The fearless Frenchman regularly travels the world in search of the perfect combination of wind and water to push the barriers of speed. In November of 2013, he set the world record at 56.65 knots, over 100kph. This coming November, he'll try to go even faster.
5. Jamie Barrow, snowboarding (behind a plane)
Risk: Losing an edge, eating pavement
While almost all of these speedsters take significant risks, going this fast, this close to the pavement might be the most dangerous of all. Pro snowboarder Jamie Barrow from Britain grabbed a tow handle that happened to be attached to a jet plane, and told the pilot to hit the gas. The result? A world record for speed on a snowboard. Check out the full-length video here.
6. Paul Larsen, speed sailing
Speed: 65.45 knots
One might question whether the unwieldy-looking Sailrocket is actually a sailboat, but one thing there is no question about: it's fast. Pilot and project manager Paul Larsen steered Sailrocket to a stunning 65.45 knots in Walvis Bay, Namibia. He and his team are currently working on the third version of the boat, which they hope will go even faster.
7. Felix Baumgartner, skydiving
Challenge: Getting to 127,852 feet above the planet
Felix Baumgartner's jump from space broke a number of records and seriously advanced scientific knowledge, but for this purpose, we're purely focused on speed. Top speed was 833.9mph, or 1342.03kph, as Baumgartner hurtled towards the earth (free flight duration? Four minutes and 22 seconds.)
