Spindata is a system for ranking time trial results across the UK by using time and relative position to others.
In fact, Spindata has been developed to recognise the achievements of all riders, whatever their ability. There are many ways to get more from your time trialling with Spindata...
Every Wednesday evening Spindata picks up the start sheets for forthcoming events from the CTT website and predicts the results for riders who have a previous result scored on Spindata.
Results are processed on the Wednesday after they are published on the CTT website:
Every rider who completes an open time trial in which at least 10 ranked riders also finish will receive a score for their ride.
If this is your first result then this score will be used as your overall ranking score and compared to everyone else with a current ranking to determine your category and predict your time for your next race.
Spindata groups riders into categories based on their ranking, with A being for the fastest riders and E for the slowest.
Each category A to E is further broken down into sub-categories numbered 1-20, thereby giving a total of 100 subcategories from A1 for the very few fastest riders to E20 for the slowest.
Categories can be used by race organisers to provide a set of prizes where everyone has a chance to race for a prize rather than just the fastest few in the race. But if they don't, then Spindata will still list the fastest three riders in each category A-E in the list of awards for each race - well done if you win an award for your category.
Spindata is incredibly welcome in providing both a performance benchmark and an incentive. It gives a really good indicator of how you've performed in an event relative to the field, whatever the conditions: you can look at a disappointing time but then see that you've done relatively well.
The ranking and categories are a genuine incentive. I'm bizarrely pround of being a "B cat" in my mid-60s, and am prepared to fight to keep that.
Knowing who is ranked around you and is expected to place around the same part of the field is also motivating. It has helped me meet new people and put names to faces, which makes TTs a more rewarding experience.
As someone who loves looking at numbers, be it my mediocre power data or scrutinising result sheets looking to see how I think I could have done in an event I didn’t even ride, I really took to Spindata.
I started riding open TTs regularly in 2019. My target in that first race was to ride under 25 minutes and not to get caught for 7 minutes by the scratch rider – this should give you an idea of my ability levels at the time. When I discovered Spindata I immediately saw it as something that I could use to monitor and track my progress. Being able to confirm that I had ridden a good ride (or indeed a bad one) was really useful, and the motivation of moving up the rankings was great.
I started off as a D4 and am now at a C1 – my target being to get into the B group. Back in September 2020 I felt disheartened not riding a PB on the same fast course on which I rode my PB the year before, despite doing what I felt was a much better ride. Being able to assess my ride against my peers and realise that I had performed far better than the year previously when I rode my PB was a big motivator. It really helps to drum home that your finishing position is a much better indication of how well you rode than getting a PB because the weather was favourable.
Spindata is very complex under the covers and the information above provides only a very high level overview of how Spindata works.
Different people will want to know different levels of detail about how it works, and we want the Spindata rankings to be as transparent as possible.
If you want to know more then please check out our FAQs which give much more detail.
The concept and the processing that produce the rankings are the work of Nick Wild, and the website is developed by Roger Clarke, both members of Tyneside Vagabonds Cycling Club.
We are open to collaborating with others, and we have an API available for use. Please get in touch via our contact form.
