Crickles in 2025

At the time of writing, the Crickles Navigator remains off air. Happily, I can confirm that there will be an initial new version launched before too long. While I’m still working through many details, the platform from which Crickles will source data – previously Strava – will now be the excellent Intervals.icu service, as proposed by a number of Crickles users. If you’d like to be notified when Crickles is re-launched, you can either follow updates on this website or email me at ian@crickles.org.

Switching from Strava to Intervals.icu provides an opportunity to share insights and information more openly. It may be useful to think about this in the following streams:

1. Data analysis and methods
   Sharing the reasoning behind each of the Crickles models, along with the techniques and calculations that implement them.
2. Learning from the data
   Unlike Strava, Intervals.icu does not claim that your data belongs to them. Going forward, this enables us to generate and openly share insights into exercise and fitness while fully respecting user privacy.
3. Health and training
   For users, coaches, or anyone looking to improve their fitness tools, we aim to make it easier to do so with Crickles. This could include enhancing the existing analysis in the Navigator, introducing new features, or making data accessible for users’ own analysis.
4. Technology
   Making these tools and techniques available – usually on our website – comes down to technology. Broadly, this breaks down into: (a) getting the data, (b) analysing the data, (c) building the user interface, and (d) managing infrastructure and dev ops.

For people of all backgrounds with a genuine interest in Crickles, I’m happy to share, explain, and discuss any of these topics. If you’d like to learn more about – or contribute to – one or more of them, please do get in touch to indicate your interest.

In the meantime, I’d encourage anyone who does not have an Intervals.icu account to get one. Please be sure to get your sports data on Intervals.icu directly from your devices as any data that is processed by Strava remains unusable by Crickles. Also, could anyone who has not previously taken our short heart health survey please do so.

Many thanks and Happy New Year!

Ian
