Blog

 

During the last few weeks we've added quite a few "predicted times" to the site.
 
For example, you can now:
- see some predicted times for all your sports in your blog view - http://www.runsaturday.com/Profile/Blog
- use our running race time predictor to estimate race performances across different distances, given inputs like your age, your gender and a previous race performance
- use out triathlon race time predictor to estimate triathlon race performance from input statistics likes some swim, bike, and run times, and some guesses about the hilliness of the courses.
- see a vdot estimate (an esimate ot V02) for your runs in your blog view - http://www.runsaturday.com/Profile/Blog
 
To achieve this new functionality we've used 5 prediction techniques:
- Riegel
- Age-Grading
- V02 Max
- Cameron
- Purdy
 
You can see all these side by side on our race prediction tool  - http://www.runsaturday.com/Tools/Running_Race_Calculator
 
Further, we've taken some of these techniques and adapted them beyond running to other sports such as swimming and cycling, taking into account some observations of the different physical properties of those sports - e.g. see http://www.runsaturday.com/Tools/Triathlon_Race_Calculator
 
For the rest of this post, I'll try to offer an explanation of how we've worked out some of those predictions. For further information I highly recommend runningforfitness.org who've assisted us with information and content for this part of our site. Indeed, I'll even be relying on some of their explanatory content for parts of this blog post.
 
If you want even further information, then runningforfitness is also available as a book - http://www.amazon.co.uk/exec/obidos/ASIN/0713651393/runningforfit-21

As the array of runsaturday Apps continues to grow, we're continuing to see more and more people add pages to their blogs to show off their data.

We love it!

Here's some more options, including some very flashy charting and some TRIMP action for your blog.

The TRIMP Studio lets you analyse your training and your planned training in terms of Training Load.

Put simply, Training Load has two effects:

- over a long time period, training makes you fitter
- over a short time period, training makes you more tired

These two effects are "measured" (guessed!) using two metrics:

- CTL - Chronic Training Load - is a measurement at the long term effect of training
- ATL - Acute Training Load - is a measurement at the short term effect of training

Lots of new features were released over Easter:

  • equivalent pace estimates for all your training (see these on your blog view)
  • vdot estimates for your run performances - see these in your blog view (run only - and really these only make sense for your races!)
  • a new applications page for your profile
  • a new applications page for each of your activities
  • Heart Rate zones for your training
  • A new Heart Rate display for each of your activities - including a new pie chart and a new line chart
  • TRIMP data - see separate blog and Talk posts for lots of details
  • A data interface (JSON) for your training plan data - used in the new TRIMP studio application
  • Groups can now see their training by time and by all sports - as well as by distance


More will be coming soon :)

TRIMP is TRaining IMPulse - the idea is to give a measure of how hard you are training.

Some good articles on this are available at http://www.pponline.co.uk/encyc/training-schedules.html and http://www.pponline.co.uk/encyc/training-plan-monitoring-your-training-intensity-40879

RunSaturday currently offers 4 different ways of calculating a TRIMP measure:

  1. BASIC - A simple TRIMP using Heart Rate and duration of exercise
  2. RPE - A Rate Of Perceived TRIMP - calculated using your own guess of how hard you have worked.
  3. Bannister TRIMP - using the Bannister formula on average Heart Rate
  4. Zonal Bannister TRIMP - using the Bannister formula on individual Heart Rate zone

This post provides information on these calculations - plus provides an introduction to how runsaturday provides further metrics, including estimates of Chronic and Acute Training Loads (CTL and ATL)

RunSaturday is all about sharing your data.

If you own a blog or website - whether it's just for you or for your group, then you might want to show your data on that external site.

Our sidebar scripts help you do just that.

Let us know what you think of these and what else you want - we love open data and want you to use your data.

Thanks, Aristos!
