The vV̇O 2 max of world class middle- and long-distance runners may exceed 24 km/h or 2:30/km pace (15 mph or about 4:00/mile), making this speed slightly comparable to 3000 m race pace. For many athletes, vV̇O 2 max may be slightly slower than 1500 m or mile race pace. [citation needed]
That is, 7.92 units of distance are equivalent to 1 unit of climb. For convenience an 8 to 1 rule can be used. So, for example, if a route is 20 kilometres (12 mi) with 1600 metres of climb (as is the case on leg 1 of the Bob Graham Round , Keswick to Threlkeld), the equivalent flat distance of this route is 20+(1.6×8)=32.8 kilometres (20.4 mi).
A pace is a unit of length consisting either of one normal walking step (approximately 0.75 metres or 30 inches), or of a double step, returning to the same foot (approximately 1.5 metres or 60 inches). The normal pace length decreases with age and some health conditions. [1]
The Léger test requires the first level to be run at 8.5 km/h. Some organizations require it to be run at 8.0 km/h. Note that the second level is always [4] run at 9.0 km/h. Also, speeds at subsequent levels always increment by 0.5 km/h. The impact of this variation is insignificant as almost all runners' scores easily exceed level 1.
Peter Riegel (January 30, 1935 – May 28, 2018) was an American research engineer who developed a mathematical formula for predicting race times for runners and other athletes given a certain performance at another distance.
These 12 pairs of running shorts for men from brands like Tracksmith, Ten Thousand, Janji, Lululemon and more will make every mile that much more comfortable.
The individual with the higher VO 2 max is running at a lower intensity at this pace than the individual with the lower VO 2 max is. [ 3 ] Some studies measure exercise intensity by having subjects perform exercise trials to determine peak power output , [ 4 ] which may be measured in watts , heart rate, or average cadence (cycling) .
It is common to compare the energy expended to run at a given fixed speed, usually by measuring oxygen consumed while running at a fixed speed (ml/kg/min). [8] This method does provide a comparison of economy at this given speed, but may often not provide an adequate representation of economy as a predictor of performance. [ 8 ]
