Under Armour HOVR Machina<br />

Bonking. For a runner, it’s<br />

the moment when they crash<br />

into a glucose-starved wall<br />

of fatigue. Observing how<br />

entrants ‘bonked’ at the<br />

2016 Boston Marathon, US<br />

sports brand Under Armour<br />

realised that understanding<br />

the phenomenon could<br />

unlock the secret to<br />

becoming a better runner.<br />

<strong>The</strong> company was<br />

uniquely positioned to tackle<br />

this challenge. In 2013, it<br />

purchased MapMyRun – a<br />

social fitness network that<br />

lets runners track sessions<br />

through a smartphone app<br />

and compare them with<br />

millions of others. <strong>The</strong>n, in<br />

2018, UA released the first<br />

HOVR Connected running<br />

shoes, fitted with sensors<br />

that measure the wearer’s<br />

cadence, pace, stride and<br />

speed and then feed those<br />

metrics to MapMyRun.<br />

<strong>The</strong> Machina is the latest<br />

evolution of the shoe. <strong>The</strong><br />

semi-caged midsole ensures<br />

flexibility while protecting<br />

the sensors. And it’s how the<br />

latter processes the data it<br />

gleans that sets these shoes<br />

apart. From studying years<br />

of running stats, UA noted<br />

clear differences between<br />

the performance of optimal<br />

and suboptimal runners.<br />

Comparing a HOVR wearer’s<br />

running style with a<br />

hypothetical best, a new<br />

‘Form Coaching’ system<br />

feeds back real-time<br />

personalised guidance,<br />

fine-tuning technique,<br />

minimising injury and<br />

gamifying their run.<br />

What did Under Armour<br />

learn? By specifically<br />

observing marathon runners<br />

(anonymously pinpointed by<br />

date, location and distance),<br />

huge clusters of comparable<br />

long-distance running data<br />

were collected. <strong>The</strong> results<br />

showed that runners with<br />

huge variance in their<br />

cadence (steps per minute)<br />

compared with stride length<br />

performed worse, while<br />

those with consistent<br />

cadence-to-stride-length<br />

ratios completed races<br />

faster and more<br />

consistently. Maintaining a<br />

stable pace, it turns out, is<br />

the key to beating the bonk.<br />

<strong>The</strong> Machina mixes<br />

the cushioning of a<br />

long-distance trainer<br />

and the lightness of a<br />

sprint shoe. A carbonfilled<br />

front-foot spring<br />

plate delivers energy<br />

back into each step<br />
