RiTMO Formula


Improvements to the RiTMO Formula Coming Soon

After several weeks in Beta and with almost 8 million kms of riding already uploaded , the formula used to calculate our RiTMO ratings is about to be updated,  making it better and more meaningful  for everyone.

The boffins have been busy analysing the staggering amounts of ride data already uploaded to RiTMO and, in the next week or so, their first update to the RiTMO formula will be released.  It’s a big change, involving some mind-bogglingly complicated maths but, in plain English, here’s what you can expect to see from the new formula…

Easier on hilly routes

When we head for the hills and especially the high mountains, RiTMO currently judges us too harshly. The new RiTMO formula makes a more generous allowance for climbing, especially when a great deal of climbing is involved. So for hillier rides, you can expect RiTMO scores to come down (or get better).

Harder on flat routes

At the moment, it’s easier than it should be to get a good RiTMO score on flatter routes – it’s too generous if you like. With the new formula, the scoring will get tougher on flatter routes, so RiTMO scores on flatter routes are likely to go up (or get worse).

A bit tougher overall

For most of us, RiTMO will probably feel tougher overall because most of us ride flatter routes more often than mountainous ones. So, it’s quite likely overall average RiTMO Ratings will go up (or get worse) for most people

It’s not you; it’s the formula

At first, seeing your score go up may feel a little dispiriting. But, remember, if it does, you haven’t of course suddenly got worse at riding, it’s just the recalibration of the RiTMO scale, to make it better and more meaningful for everyone. Plus, we’re all in the same boat of course, which is what really matters.

A better, more universal RiTMO

Much as Chris Hoy and Chris Froome are at once ‘equally remarkable’ yet ‘entirely different’ cyclists, a RiTMO of 5 gained on a short, flat route should be an equal achievement to a  5 gained in the mountains. That’s the nub of what RiTMO does: it’s a way of comparing performances on different routes with different levels of climbing on one scale. This update will make RiTMO better at doing this, which we hope you agree, is a good thing all round.

    I thought the changes were going to happen a few weeks ago? Any new date?

    My average rides are hilly (today was climbing >450m in 23km). However, despite a 23kph average I get a 19.0 score... This can't be right considering my 22km ride averaging 25kmh gets me a 14 score.. When are the changes due; soon I hope?

    Any indication of when the change is coming? Or has it happened and just not changed any of my scores. If it has happened, it must still be a bit flawed as my highest scores come from flat rides, but the hilly rides I do are MUCH harder.

    why do i not get a ritmo score when i manually add an activity? not had one since Strava left us.....

    Just wondered if the re calculation is coming, or did i miss it when it happened! I have been waiting for my score to worsen, and as yet it hasn't!What's the news? Also, how is the RiTMO app for Android coming along? I am really looking forward to getting that on my phone. It has been a bit of a pain manually adding all my rides from Strava to the CW website!

    Definitely think this change is needed. My RITMO scores on hilly rides were rubbish compared to my flat scores - even though I was far more knackered at the end of the hilly ones. - Good idea.

    Any chance we will see a 'fixed' option? Probably more folk ride fixed than unicycle.....

    I live on the edge of the Cairngorms, so I don't ride flat routes very often!

    Do we have a date yet? Glad its retrospective too!
  11. By Grant Stevens 9 months ago

    will it retrospectively recalculate previous scores?
