We’re into hot day season, with a heatwave arriving in the UK it feels like a good time to talk about density. The density of the air is essentially “how many air particles exist in each metre cubed of air”. This is the cause of a day feeling slower than it should be. It’s usually … Continue reading “What makes a slow day?”

Yesterday, we predicted a winning time of 42:54 in the Giro d’Italia stage 10 time trial. Ganna, unsurprisingly, won the stage but he did so in a time of 45:53, almost 3 minutes slower than we predicted the winner would go. In his daily vlog, Victor Campenaerts said to Ganna that Visma had predicted his … Continue reading “Getting a prediction horribly wrong”

We’re going to put our money where our mouth is and try to predict the winning time of the Giro d’Italia Stage 10 TT then, after the race we’ll take a look at how we did and what this means for the first Tour de France time trial. This blog will not predict who will … Continue reading “Giro d’Italia TT – predicting the winning time”

If you’re allowed to share the work, why does a TTT feel so much harder than an individual time trial? This is, of course, dependent on the team. I’ve been in team time trials where I’m the strongest rider, and team time trials when I’ve been the weakest rider yet the hardest TTTs are always … Continue reading “The physics of a Team Time Trial”

When planning my week, I used to use my Apple weather app to decide which days I’ll ride inside vs outside yet increasingly, as winter turns to spring, I find myself sat on the turbo looking out the window at a sunny day. This is the result of weather forecasts being weighted toward pessimism. If … Continue reading “Don’t believe the forecast”

Club TTs are a fun affair. Collecting numbers out the back of someone’s car, pinning each other in a freezing cold car park, handing over cash and lining up in a lay-by. To the uninitiated, it could look a bit odd. Recently, there was a club TT in my village so I can attest to … Continue reading “How to make the most of a club time trial”

They’re often cold, statistically windy and most definitely slow (according to the laws of physics) – so why on earth should anyone do an early season time trial? Well, there are many reasons it’s worth embracing a slow time and a cold morning and this blog will talk you through them. Here in the UK, … Continue reading “The early season time trials”

The 2026 edition of the men’s and woman’s MSR is taking place this weekend and while everyone is wondering who will win the direction of the wind has caught our eye here at myWindsock HQ. Of course, we pay more attention to this sort of thing than the cycling journalists typically do who are often … Continue reading “Milan – San Remo 2026”

As you ride, both wind speed and wind direction shift relative to you, meaning one of the key factors in aerodynamics—the yaw angle—rarely stays consistent for long. Despite this, manufacturers often claim they have optimised their designs for particular yaw angle ranges. Some even argue that certain tube and rim shapes can behave like sails, … Continue reading “What is yaw angle?”

It’s no secret that here at myWindsock we love a TT and with 5 time trials on the first Sunday of March this year it’s fair to say we are well and truly back. Early season Time Trials aren’t all about PB times though, as there’s a lot of factors that can make them a … Continue reading “The early season Time Trials”
