This isn't an update from me on the Runscribe, which I started using back in October last year, as I haven't been running - let alone running with my Runscribe - but rather an important update from the people who make it.
They have just launched a new website "Running Unraveled" which aims to use the anonymous crowdsourced data collected from all the users of Runscribes around the world. In particular, they have finally published the results of a study of those who ran the New York Marathon last year with one, in which I can count myself (I am the 3:02 data point).
The other interesting development is that they have added a couple of new metrics to the dashboard, as well as a comparison to the Runscribe community of where you stand in terms of "efficiency" and "shock". Shock is a total measure of the 3D G's you have undergone multiplied by the number of steps you have taken. Efficiency (I think) is comprised of some mix of step rate, contact time and flight ratio. This last - flight ratio - is an interesting addition which measures the ratio of the time in the air to the total time to take a step. The results from the New York Marathon appear to show a very strong correlation between (lower) race times and (higher) flight ratios, as one would expect. What is perhaps striking (if you'll forgive the pun), is how much variability there is in flight time between elites (50%), competitive runners (25%) and fun runners (10%-0%).
If I ever get back to running, it will be interesting to see how my "flight time" compares to last year. It will also be interesting to see how this metric differs between a similar paced run on the treadmill, on a track and on a trail.
