On the warm and sunny morning of Sunday 26th May Jacob Puzey ran a largely solo effort to win the Calgary Marathon 50k race in a time of 3 hours and 7 minutes. During the race Jacob was wearing a tiny set of sensors that were measuring his running gait from the gun to the tape. In this short article … Read More
NYC Marathon 2018 (Part 2) – ShoePrints
We were fortunate enough to collect data from 36 different runners at the 2018 NYC Marathon. Combined, they covered 943 miles in 1,356,559 steps, with RunScribe pods dutifully recording every single step. … and no two ShoePrint Contact Signatures are the same …
NYC Marathon 2018 (Part 1) – The Vaporfly Phenomenon
We were stoked to be back in NYC for the 2018 Marathon – getting pods out to over 50 runners to capture their data as they ran on what would turn out to be a perfect day in NYC! Positioning ourselves in Central Park at the Mile 25 marker, we watched (and waited), looking for pods while runners flew past … Read More
Inside Trail – Santa Cruz – Race Report
The week before our RunScribe Plus announcement, we had the pleasure of getting out from in front of our screens, heading down to Felton, a little town outside of Santa Cruz, CA. Inside Trail hosts a series of trail runs, with distances typically ranging from 10K to 30K, with some races including a 50K. We took down 12 demo sets, … Read More
The Unescapable Fatigue Effect
In an earlier article, I discussed the mechanics of how fatigue impacts pace during a marathon, but what happens to other metrics like ground contact time, flight ratio and impact characteristics? We know these metrics are predictably affected by running speed in an unfatigued state. As running speed increases, impact Gs, pronation, pronation velocity and flight time usually increase. Contact time … Read More
Achieving Pace Consistency in Endurance Running
Pace consistency is at the heart of a runner’s training and is important for endurance races like the marathon. Coaches help athletes find their rhythm early as to not burn energy. Achieving pace consistency seems simple, but mechanically our bodies make constant and subtle adjustments. We know pace is a simple equation: Pace = Stride Length x Stride Rate. But … Read More
Deep Dive into the 2015 NYC Marathon
Motivation for running a marathon is varied and sometimes elusive. Each runner has a goal – to place, hit a PR or just finish standing up. The NYC Marathon is the ultimate collection of motivations – every level of athlete doing whatever it takes to hit that goal. We wanted to capture those stories through the lens of running data. … Read More
The Finish (NYC 2015)
The finish is where you dig deep, give it everything you’ve got, knowing that it will be over soon. In Ellie’s case, we see the picture of an elite athlete who is holding on as hard as she can, in spite of a loss of efficiency (Flight Ratio started at 25% – and dropped down to nearly 15% toware the finish). … Read More
The Wall (NYC 2015)
The Wall is every runner’s torment.When will I hit it? Will I recover? How? Even an elite, consistent runner like Ellie, isn’t impervious to The Wall. At around mile 21 (35k), Ellie’s pace drops slightly as her Flight Ratio (an efficiency indicator) continues its slow downward trend (it’s fortunate that Ellie starts at elite levels!). But what is interesting is … Read More
The Bridge (NYC 2015)
The Queensboro Bridge at mile 15 (25K) is considered one of the toughest points of the course, and with no spectators allowed on the bridge, it’s also the quietest. Our elite runner – Ellie – slows her pace just slightly as she shifts to a more mid/fore-foot strike going up and over the bridge. We can see that in both her higher … Read More
