Inside Trail – Santa Cruz – Race Report

timclarkAt the Races

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

UNLV Research Study — Validation

timclarkValidation

UNLV/RunScribe Study — Summer 2016 Purpose: The primary purpose of the project was to compare RunScribe metrics with high speed video and motion capture data measurements over an expanded range of running speeds and fitness levels. A secondary purpose was to investigate possible relationships between RunScribe metrics and running economy. Methods: Subjects Subjects: 23 runners. The runners represent a wide … Read More

Improving Run Efficiency: What Research Tells Us

timclarkMetrics, Research

What is Run Efficiency? If you study a slow-motion video of an elite distance runner they seem to bound-along effortlessly, exerting little effort to maintain speeds that mere mortals could hardly achieve sprinting flat-out!  Efficiency, in a general sense, implies doing something in the most efficient manner, i.e. wasting the least amount of resources.  Being able to run at a … Read More

Case Study: The Impact of Shoes on Asymmetries

timclarkUser Stories

With the release of the RunScribe Shoe profile, runners now have the ability to quantify how they perform in different shoes, workout type and terrain. By understanding how mechanics change with these variables, runners can make smarter training decisions and shoe choices. Asymmetries are a natural part of any runner’s stride, but in this example, the runner has a long … Read More

Mortals vs Elites – A Look at Stride Mechanics

timclarkResearch

If you’re like us you’ve been glued to a screen watching the world’s best runners compete on the largest stage. Elite runners seem other-worldly, making unimaginable paces look easy. We know there are a laundry list of characteristics that make someone elite, but what about their mechanics? Do they run differently than us? Over the past year, a handful of elites have … Read More

Case Study: Asymmetry & Injury In A Physiotherapy Setting

timclarkTraining & Rehab, User Stories

At Physiohaus we came across RunScribe via a trip to Boulder USA. I’m an avid runner and therapist who has had just about every injury going. For me RunScribe offered something different to typical gait analysis – gait metrics from your actual run! Not treadmill or video analysis in a laboratory setting but field data from how you specifically move … Read More

RunScribe Validation Research Study

timclarkValidation

Ground contact time during running is defined as the time elapsed between initial ground contact and toe off. The gold standard in measuring ground contact time during running is high speed video, where heel strike and toe off are manually digitised to find the time elapsed. This system is limited for reasons including the time consuming process of manual digitisation, … Read More

The Unescapable Fatigue Effect

timclarkAt the Races, Research

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
