Riding in a group: the skills nobody explains to beginners

Riding in a group is the highest-leverage skill in road cycling and almost nobody teaches it. New riders are handed a club run start time and left to work out, at 35 km/h and thirty centimetres off a stranger's wheel, what everyone else appears to already know. The result is either a frightening morning or a slow one at the back, and frequently both.

None of it is complicated. It is a short list of physical habits and an even shorter list of social ones, and this article sets both out plainly.

Why the group is so much faster than you alone

Above about 25 km/h, most of what you are fighting is air, and shelter from it is worth more than fitness. This has been measured repeatedly and the numbers are larger than most riders expect.

McCole and colleagues measured the oxygen uptake of cyclists riding outdoors and found that drafting reduced it substantially — and that the deeper into a group you sit, the bigger the saving:

Wind tunnel and CFD work tells the same story from the engineering side. In a study of two riders, the trailing rider's drag fell by up to 27% at close spacing — and the leading rider's drag fell slightly too, by around 1–3%, because the rider behind alters the wake. Drafting is not purely parasitic.

The most striking figures come from the peloton. High-resolution CFD of a 121-rider bunch, validated against wind tunnel tests, found that riders in the mid-rear experienced drag as low as 5–10% of an isolated rider's — far larger reductions than the older small-group studies had implied. That is the real reason a bunch you cannot hold seems to ride away effortlessly: the riders in it are not working as hard as you are.

Holding a wheel

The skill everything else rests on. It is not about being close — it is about being predictable, and closeness follows from that on its own.

• Look through, not down. Focus a few riders up the road, with the wheel in front in your peripheral vision. Staring at the tyre in front means you learn about every change a second late.
• Overlap nothing. Never put your front wheel alongside someone's rear wheel. If they move sideways, you go down and they do not. This is the most common way beginners crash a group.
• Ride slightly offset. A few centimetres to one side of the wheel in front. You still get the shelter and you have somewhere to go.
• Soft elbows, hands on the hoods. A locked-out rider transmits every twitch into a steering input. Stay relaxed and the bike absorbs things for you.

Start further back from the wheel than feels efficient and move up as you get comfortable. Half a metre of shelter is most of the benefit and all of the safety margin. A rider sitting 30 cm off a wheel they cannot read is not being brave, they are being a hazard to five other people.

Braking, or rather not braking

In a group, braking is a message sent to everyone behind you, and the message arrives late and exaggerated — each rider brakes a little harder than the one in front, so a gentle touch at the front becomes a panic grab at the back. This accordion effect is the mechanism behind most bunch crashes.

• Scrub speed without the brakes first. Sit up, ease off the pedals, move a few centimetres into the wind. That is usually enough.
• If you must brake, feather it. Light, brief, both levers, no grabbing.
• Never brake while overlapped. Get clear of the wheel beside you first.
• Anticipate. Junctions, roundabouts, gradient changes and traffic lights all come with warning if you are looking up the road rather than at a tyre.

Rotating

A group shares the work by rotating through the front. In a simple through-and-off, the rider on the front does their turn, pulls aside, drifts back along the line, and rejoins at the rear. Three points beginners consistently get wrong:

• Do not accelerate when you hit the front. The most common error by a distance. Hold exactly the speed the group was already riding — check your speed or power as you take over if you need the reassurance.
• Take a short turn, or none. A thirty-second turn ridden smoothly is worth far more to the group than a five-minute turn that surges. If you are struggling, say so and sit on. Everybody has done it.
• Pull off into the wind. The rotation direction is set by where the wind is coming from, and someone in the group will say which side. Ask before the first turn rather than guessing at 40 km/h.

Signals and calls

You are the eyes for the riders behind you, who can see almost nothing. Everything you would react to instinctively on a solo ride has to be passed back instead.

Local convention varies and some clubs have their own gestures, so ask at the start rather than inventing one. Two rules are universal: signal early, and never signal instead of looking — a hand off the bars in a bunch is itself a risk, and a shout is often the safer option.

The etiquette that actually matters

• Turn up with a working bike and enough food. A mechanical or a bonk is everyone's morning, not just yours.
• Know the route, or at least the distance and the group's pace. Turning up to the wrong group is the most common cause of a bad first club run.
• No half-wheeling. Riding a few centimetres ahead of the person beside you drags the pace up all morning and irritates everybody.
• Nobody gets dropped on a social ride. If that is the group's stated culture, honour it — and if you are the strongest rider present, your job is the front, not the sprint sign.
• Say something. New riders who announce they are new get looked after. Riders who quietly pretend to know the conventions are the ones who cause problems.

If you want to build the handling confidence somewhere lower-stakes first, riding closely in a virtual bunch is a reasonable rehearsal for the rhythm of a rotation, if not for the physical reality of it — Moveee Indoor runs group sessions in the browser. It will teach you nothing about holding a wheel on a wet descent, and you should not pretend otherwise, but it will make the pattern of taking a turn and drifting back familiar before you first do it for real.

Your first few rides

Sit in the middle of the group, not the back — the accordion effect is worst at the rear and the shelter is better in the middle. Do not take a turn on the front until you have watched several others do it. Ask someone experienced to ride with you and narrate what is happening. And accept that the first one or two rides will feel like a great deal of concentration for very little enjoyment. That fades quickly, and what replaces it is the reason most people who ride in groups keep doing it.
