A complete guide to training, equipment and race day

A time trial is bike racing at its simplest – just you, the bike and the clock. But don’t confuse simple with easy.

There are no wheels to follow, no pack to hide in, and it hurts from the moment the starter shouts “Go!” to the moment you cross the line. So let’s look at how to get better at time trialling.

The TT offers a different kind of satisfaction from bunch racing. Nobody sits on your wheel then jumps out to beat you in the last 100m. Barring a mechanical or a sudden change in the wind, the best rider wins, but more than that it’s a pure test of your ability to ride a bike fast.

Finish your first time trial and, when you’ve wiped the sweat from your eyes, most riders will have the same thought: “I want to go faster!”

Learn to hide from the wind

All the bling kit in the world won’t make you go faster if your body acts like a giant air brake.

“The rider makes up over 80 per cent of the frontal area,” says Chris Boardman, arguably Britain’s best ever TT rider, “and at any reasonable speed 90 per cent of the energy you produce goes into overcoming wind resistance.” Cut that resistance and you’ll go faster.

Keen riders can head for a wind tunnel for guidance, or you can put your TT or road bike on a turbo trainer or set of rollers in front of a full-length mirror to tweak your bike position at home.

“Making your silhouette smaller is a crude but fairly accurate way to reduce drag,” says Boardman. “TT bars bring your arms in and round off your shoulders. Dropping your body also has a significant impact for every centimetre lower you go.”

But, he says, don’t have too great a drop to the bar. “If the front of the bike is too low you have to stick your head up to see where you’re going, which makes the silhouette bigger.”

Loosen up

A full-blown time-trial bike, or even a modified road bike with clip-on aero bars, will have a more extreme riding position than most roadies are used to.

Riding with your head down, backside in the air and elbows close together doesn’t look comfortable, and to some extent it isn’t. However, a rider can use stretches or yoga to improve their flexibility. This would help you stay comfortable and powerful in your TT pose.

Physical activity expert, Professor Greg Whyte, says stretching the backside (glutes) and hips (adductors) is particularly effective.

“Lie on your back on the floor with both legs bent,” he says. “Place the ankle of one leg on the knee of the other. Place your hands behind the bent knee and pull it in towards your chest. Hold for 20 to 30 seconds. Repeat with the other leg.”

According to Professor Simon Jobson, Dean of the Faculty of Health and Wellbeing at the University of Winchester, “the big thing is habituation to the position”. He recommends training regularly on your TT bike so it doesn’t come as a shock on race day.

TT gear will help, but you don’t need to spend loads

The first job of go-faster frames or tri-bars is to get you out of the wind before they cut through the air. If you plan to use the same bike for your road riding and time-trialling, pay attention to the head tube length, says Boardman.

“A shorter head tube will make finding an aerodynamic position easier because it makes the front end of the bike lower and so helps you get out of the wind.”

You don’t have to spend a lot. Lowering the front of the bike (which might be as simple as flipping the stem to drop the handlebar position), fitting some tri-bars (from as little as £30) and buying an aero helmet (around £100) could make a big difference to your speed.

These changes offer the most bang for your aero buck. Boardman estimates a TT helmet alone saves the rider 10 to 15 watts of power at race speeds.

From here, you can start to add aero socks, skin suits, overshoes, aero drinks bottles, and even deep-section wheels and a full-fat time trial bike.

But before splashing loads of cash, remember that the best value aero upgrade is body position.
