100% Time Trialling

I’ve blogged about time trialling before, about the reduction in availability of what are deemed ‘suitable’ courses & the sustainability of sticking to the outdated model of standard distance, relatively flat courses. There are other ways of looking at measuring performance & progress in time trialling, than just looking at times at set distances, we could use a new method to modernise this side of the sport & open it up to appeal to a larger demographic than just some old guys with money for expensive funny bikes. Here’s one idea.

The % Method

Is there a way of measuring your performance & improvement across a season, on any length of course, on any terrain, against the best rider in the event?

I’m going to suggest that there really is, all it requires is an additional column in the event results. If a chump like me can easily create this extra column in Excel (I’ve just tried), it’s likely that it can easily become a standard template that organisers can record the times on, if so desired.

If riders times were displayed as a percentage of the winners time, there’s a multitude of uses we could put this information to, here’s just a few….

  • At the top of the table, the leading riders can get an idea of how form is improving or otherwise as they get closer to championship dates. If their % gap on their rivals in increasing, the training is going well, but if it’s closing, it’s time to look at improving. This can be measured not in seconds over the same distance, but in all distances in %, which allows direct comparison without taking into consideration the changes made by weather, courses & distance.
  • Any rider, in any position, can see how they’re improving relative to their closest rivals, club mates, or random benchmarks, irrespective of the course or weather.
  • If you change an aero setup or your training, a sudden increase or decrease in % against your rivals may indicate how good (or bad) the new setup or training is, regardless of the distance of the event.
  • Rapidly improving riders can be easily & quickly identified across a season or just a few weeks, a shortening of % and how it relates to not just winners, but various riders in the event will be very easy to spot, no matter where in the results the rider currently lies.

The Effect

If the riders target moves away from aiming for specific times over specific distances, then having results recorded as a percentage of winners time can help us move away from set distance courses.

We could use the type of roads cyclists generally choose to ride on, more suitable roads for cycling, we could remove the necessity to measure the courses to be exactly 10 or 25 miles, we could pick a course anywhere & retain a comparative measurement to performance against any other course. The focus could switch to reducing your % loss to the winner, or a comparison % loss to your ‘rivals’, be they club mates, enemies, chain gang buddies etc.

So if this was adopted to be included in the results, you can compare performances across various events, on different terrain, different weather, all year-long. You can see much easier which courses suit you better, or where you need to improve. Chasing specific times on different days, even on the same course can be a losing strategy sometimes. If conditions are bad & all times are slower, you may be upset with your recorded time, but in reality, your % loss to the winner may be less, you may actually have performed better in relative terms than the ‘float day’.


If we’re going to do this, it may require a little thought on how to go about it, plus exactly what you need to stick into your Excel sheet. We also don’t want to get tied up too many decimal points, 2 will suffice as I’ll show in my example below.

To keep things simple, if somebody won a ’25’ in exactly 50 minutes, that’s 3000 seconds. The minimum gap we see on results is 1 second, that’s approx 0.03% of the winners time, so 2 decimal places will be fine for every time trial up to around 3 times the winners time. So unless you’re riding one of the incredibly few 100 mile TT’s in Scotland, and your gap to somebody else is less than a second, this will work for every other TT, than that one.

As an example, here’s my revised finish sheet for the first five riders in my theoretical ’25’.


Max Tester won the event, he gets 0% allocated to him, as all winners of events do. Two minutes down was Chanty McMuffin, his % difference was 4% down on the winner (2 minutes, i.e. 120 seconds, divided by winners 3000 seconds, all multiplied by 100 to give a percentage). As we can see, Marjorie Gains was only one second down, her % loss was 4.03%, so each second is accounted for with just the two decimal places being included in the results. As we go down the results, 5 minutes equates to a 10% loss on the 50 minutes of the winner. Then we have the hour specialist, doing as he does best & riding for exactly one hour, but losing 10 minutes, which is 20%.

The formula you’d enter into the Excel file starting at cell B2 if it was laid out the same would be as follows. Then you just copy it down the page, the $ sign means those cells remain tagged to the winners time, while all others will change. Remember to format the cells as a percentage & restrict it to 2 decimal places.



In every event, we’ll have varying times, one second will have a different % value depending on the winners times. This allows a comparison, not against time, but against performance relative to the winner, which gives a very different perspective. This also allows every single competitor to compare themselves across different events, different weather conditions on the same course etc. A whole new way of thinking about things.

There must surely be multiple ways in which time trialling can be modernised, this is just one. It may remove the perceived need for standard distance courses, it may initially just allow riders to compare performances against other riders on the same course, but in different conditions. It could allow riders to see how their form is coming on as a season progresses, but if things remain the same, courses will continue to disappear & time trialling will become a forgotten discipline.
